Clash of Clans Tips and Strategy Defense #2

Welcome to Chapter 2. I sure was hoping to get this out a lot sooner than 3 weeks after Chapter 1, but stuff came up (mid terms) and I had some trouble with some tricky stuff (turret range details).

This chapter is much longer and much more detail oriented than the previous chapter. Where as I was trying to make Chapter 1: Base Defense, The Basics accessible to anyone, this chapter gets into the nitty gritty details which is probably more useful only at the higher levels of both gameplay and dedication. As such, it truly is a Wall Of Text™. I did still leave out some details that I thought were getting too specific, so if you want to know why I recommend something feel free to ask in the comments, PM me on reddit, or ask in clan chat in game of the clan I recently set up with the last patch. Now, without further ado, Chapter 2: Advanced base Defense!

2.1 Are you a tempting target? The best way to not get attacked is to not make it worth your attacker’s time. There are several things that an attacker will likely attack to get, or not attack due to the presence of.

2.1.1 Large amounts of Loot! Loot is the #1 reason people will attack at low levels. If you don’t have much to steal, you’re safe! Spend as much as you can on walls prior to starting any upgrade. Spend on removing natural decorations when the builder is available. If you don’t have a worker available, start a research project in the Laboratory (elixir) or buy decorations (gold and elixir). 
Note that gold not collected (in Gold Mine or Elixir Collector) can be stolen. 

Other ways to spend resources - Queuing units (even when your army camps are full), building spells, starting research, buying defenses (bombs/spring traps), buying decorations (flowers and flags, they will prevent enemy spawning on top of them).

2.1.2 Having easily accessible loot Accessible loot comes in two types - accessible mines/collectors and accessible storage. Both are bad. Make sure your storage is either empty or in the middle of your base. Make sure your mines/collectors are next to your walls (and therefore next to your defenses). Uncollected resources are easier to steal then collected ones - the buildings are more spread out and the buildings have lower HP.

You should also intermix your elixir collections and mines as well as your elixir storage and gold storage. If an opponent really wants your gold, and all of your mines are together in a nice line, it is much more tempting of a target as not as much needs to be invested to steal the single resource they are seeking. 

Similarly, make sure your two gold storage are not next to one another. 

2.2 Having a Good Base See Chapter 1 for details (Common issues: not protecting your defenses, mortar and air defense placement, everything-inside-walls issue, spread out defenses). Also having defenses that are significantly below the ‘normal’ upgraded amount for your trophy count/level. Here are a few more common bases and what I think of each.

2.2.1 The Standard Base The standard base follows all of the rules laid out in Chapter 1 - Defenses and storage inside of the walls, army camps, barracks, mines, extractors, etc etc etc outside of the walls. There is a single wall dividing your precious base from the hordes of horrors outside. Now What? How can you improve your base? Well this standard base is weak to giants as once they breach your wall, they can attack all of your defenses without delay. It is also weak to mass goblin attacks for the same reason - Once inside they can often outrun splash damage and steal all of your goodies, possibly leaving you with a victory, but with many less resources to spend.

2.2.2 The Pocketed Base This base has the town hall in the center, and every defense around it is surrounded by its’ own 4x4 wall. They are good against giants as the walls slow them down, while keeping the defenses are close together. They are best attacked with giants and archer support.

2.2.3 The Large Pocketed Base This base is a variant on the pocketed base, where each pocket has 2-3 structures in each pocket. It is more efficient in terms of wall usage than the pocketed base, allowing for more buildings to be placed within the walls. People who love symmetry in their bases will like the 3 pocket base, as it creates a nice spiral with no wasted space or walls. The differences between this as the Pocketed base are minimal. This base type is more common than the Pocked Base at lower levels due to lack of walls.

2.2.4 The Bulkhead Base A Bulkhead Base follows the rules laid down in chapter 1 about kicking unneeded buildings outside of the walls, then uses extra walls to segment defenses into different sections allowing for greater protection in case one section is breached (especially by giants). Bulkheads are used in large boats to prevent the entire boat from sinking in case of a leak below the waterline - The flooded sections are closed off via built in bulkheads, containing the flooding to only the affected sections. In the same way, bases use this strategy to contain (or slow) the flood of enemy troops to the breached bulkhead - Where as a single wall a breach would mean your clan is headed to destruction.

2.2.5 The Split Base A somewhat common (but poor) base defense strategy is grouping your defenses into two groups, with critical non-defensive buildings between them (Town Hall, Resource Storage). This defensive strategy seems to not violate the rules I’ve put down in Chapter 1, but it actually violates the rule of keeping your defenses too spread out. Your defenses should be able to cover each other, ideally as much as possible - keeping them in two groups should be avoided. A split base defense is very vulnerable to giant attacks as they can clean up half of the defenses without taking fire from the other half. Split bases also mean that if either side is wiped out, your critical buildings in the center are very vulnerable to a few arche

Your defenses should be able to cover each other, ideally as much as possible - keeping them in two groups should be avoided. A split base defense is very vulnerable to giant attacks as they can clean up half of the defenses without taking fire from the other half. Split bases also mean that if either side is wiped out, your critical buildings in the center are very vulnerable to a few archers attacking from that side, effectively meaning your base is half as weak as otherwise.

2.3 Funneling for Victory
Funneling is critical to getting the best results out of your splash damage dealing turrets. It basically means using buildings (mostly walls) to make your enemy go where you want it to go, and then die as you want it to die.

This is how my current base funnels enemies.

Proper funneling turns this into this

Do I need to say more? Funneling is also critical to proper trap usage. See section 2.11 below. 

2.4 Upgrading multiple defenses at the same time Your defenses don’t attack if they’re in the middle of being upgraded when you’re attacked! Try not to be upgrading 40% of your defenses at the same time. This is doubly true for splash damage buildings (mortar, wizard tower) and air defense.

2.5 Having a glaring flaw in your base
Such as a spawn point where you moved a turret out of but didn’t put anything back. Or not having an air defense turret. Or putting your air defense turret outside of your walls. 


2.6 Buildings outside walls are too spread out
At higher levels, more players start caring about trophies. If an attacker sees your base is easy to 1-star (kill 50% of the buildings) without having to place too many troops they will see you as a good target. Keep your buildings close to your walls (and defenses) to prevent this, if you care about maintaining your trophy count.


2.7 Turret Range Considerations: What can your towers defend?
One of the goals of placing less valuable buildings outside of your walls is to slow down your attackers once they are within range of your defenses. NOT to make them spawn farther back - This is of secondary priority. This section covers what that range actually means. Range in this game is also sorta screwed up - Sometimes a turret will decide it can attack a unit standing in a given square, but on another base (with identical unit and turret placement) it won’t attack. This ambiguity is why it has taken me about 2 weeks longer to post Chapter 2 than I was hoping. I still haven’t figured out why it does this.

What can and can’t be attacked without taking return fire is summarized in these pics.

Archer - Range 4 


2.8 Spawn Forcing
Spawn forcing refers to forcing your opponent to spawn further away from your important buildings, or your base in general. The objective is to attempt to persuade your opponent to attack from a different side of your base and to delay their reaction time (placing reinforcements). You can create this gap outside of your base by arranging your exterior buildings, placing extra walls, placing decorations and utilizing natural decorations. It is not recommended to use buildings to force your opponent to spawn further away, as buildings are more useful to delay your opponent once they are in range of your turrets. However, if you spread out your walls in singles (optimal distribution to create a large no-spawn-zone) wall breakers will almost never attack them. Spawn forcing allows your defenses to kill many wall breakers before they get to your walls if they are unsupported. For other wall breaker defense tips, see decoy walls below. If allowed to spawn directly next to your wall, wall breakers are able to detonate before turrets can strike, even if the wall breaker would normally be one hit by the turret. 


2.8.1 Trick Spawns
Trick spawns are ‘mistakes’ in a spawn forcing situation. Usually a single hole, they are closer to the center of your base the rest of the spawn force allows. However they are intentional and you should make sure you have turrets (especially mortars) barely within range of the spawn square in question.


2.8.2 Why use trick spawns?
Spawn tricks are fun (I’ve had an opponent put down 31 archers in a trick spawn just to have them all die to a single mortar hit - they didn’t opt to continue attacking). Normally they don’t matter but occasionally they help. If created without care, they can allow your opponent an advantage (such as if they can deploy wall breakers). It is inadvisable to rely on traps to defend a trick spawn - if you get attacked twice in a row they won’t be there the second time, plus a smart attacker will place a single unit in the square in question to test for traps.


2.9 Messing with Wall Breakers
Wall breakers are often used in conjunction with giants to get them through the outer walls faster. Here are a few tips to mess with the Wall Breaker AI.


2.9.1 Decoy Walls
Decoy walls are segments of walls of at least 8 that wall breakers will target if they are closer than your real walls. They can also be used to funnel archers and barbarians into taking lots of splash damage from mortars and wizards. Segments of 7 or less don’t seem to work most of the time (seems to be partially based on spawn proximity). If you do further testing and discover any additional details, please report back (for science).


2.9.2 Outer walls with Buttresses
When used in game they look like this. The wall breaker will attack the buttress rather than the walls. Giants will ignore them and proceed straight to the inner walls. Only once the nearby buttress is destroyed will the Wall Breaker target the main wall. This works especially well with spawn forcing, as the farther away the wall breakers spawns the more likely they will target several buttresses, rather than several targeting one buttress and then the surviving ones re-targeting onto the main wall. They can also be combined with Decoy Walls - See pictures of my base in the funneling section for how I use them in such a situation.


If you're curious about the name, buttresses are these things on churches. They support the walls from outside of the church. 


2.9.3 Using extra walls for Buffering

Visual of buffering
If you have extra walls you can also use them to protect your defenses from archers. They simple prevent archers from getting close enough to fire, however they do cut down on the number of buildings outside the wall your turret can protect so I generally only recommend this for situations where you 1) DON'T want archers attacking form 2) have walls to spare 3) don't have buildings which can defend your turret instead. This situation can be considered the advanced method of 'Defending your Defenses' (from Chapter 1) but is generally not viable to lower level players due to the number of walls necessary.

Clash of Clans Tips and Strategy Defense #1

Welcome to my Clash of Clans Strategy Guide. If you're just interested in the good stuff, skip down to below. Still with me? Good stuff. I'm starting this guide so I don't need to keep writing out the same suggestions for people when they want their bases reviewed. I'll still give specific details, but now I'll be able to link them to one place. Eventually this guide will probably be on the Reddit Wiki system, once it is released. Please do not post this guide without permission (just PM me and ask) and without crediting me. 

I'll try to keep updating this guide, and I'll try to keep it not so wordy, and have images, especially in the beginner chapters. Please excuse my [lack of] MSPaint skills. If you have advice, images, comments, suggestions of your own, please feel free to comment and I'll incorporate them.

1.3.1: Where should I place my Mortar?
1.3.2: Where should I place my Air Defense?
1.4 Don't try to stuff everything inside your walls
1.4.1 What should I keep outside my walls?


Chapter 2: Advanced Base Defense

1.1: How to Defend your Defenses
Walls are good. But walls are not the only part in a super awesome base. The #1 mistake I see new players (or not so new players) doing is placing their defenses so they can be targeted by archers spawning outside of the walls. Don't make this mistake.

The difference between 'Decent' and 'Great' has to do with the way units decide which building to attack next. It it too complicated to get into here (this 'basics' section) but I think I'll cover it later in more detail.


The buildings protecting your defenses do matter - Mines/collectors will have more HP than Barracks/Builder's Huts.


1.1.1: Oh God! Enemies Can Spawn There Too?! Not good! Unless it's your enemy! from wadely
Yes, enemies can spawn around the ring of your base. No, you can't build there to stop them. 

1.1.2: Holes in bases are bad, mmk?
When you move any building or wall (but not decorations, it shows you white lines one space larger in every direction than that building. This is showing you where enemies can spawn. Make sure you don't have any holes in your base to let them spawn inside your walls. That would be bad. I will write about how to leave intentional spawn spots in your base later, in the advanced base defense chapter. 

1.2: Overlapping Defenses
Not Good.


Another common mistake is placing all of your defenses widely spread apart to cover as many buildings as possible. Dies very easily to several giants. Or to groups of infantry, especially archers. Or to balloons. Which I guess it means it just dies to everything. This often goes along with 'Trying to stuff everything inside your walls' covered later. 

1.3: Splash Damage: It's your friend!
Mortars (and later wizard towers) are your first and last line of defense against mass infantry attacks. A mortar's damage is only limited by how many troops your enemy puts down and how well you funnel them into where you want them. A fully upgraded mortar (level 6, total cost 3,752,000 gold) will do 45 damage in one shot to the unit it targets. In the same amount of time (5 seconds) an archer tower (level 1, total cost 1,000 gold) will do 55 damage to the unit it is targeting. What does this mean? It means you need to make sure your splash damage defenses are hitting enemies in groups and are protected. How do you get them to hit enemies in groups? Put then in the middle of your base - As soon as the enemy destroy a wall and funnel through it, they will be nice and bunched up for the mortars. 

1.3.1: Where should I place my Mortar?
Somewhere very protected. Probably in the middle if your base, ideally with it's own wall around it. 

1.3.2: Where should I place my Air Defense?
In the middle of your base. Mass are attacks are rare (due to time to build), but not unheard of. A single, upgraded anti air turret is a wonderful deterrent, but it should be placed in the middle of your base. More specifically, it should be placed such that, if a mass balloon attack comes, It won't be the first, second, or third defense they kill.

1.4: Don't try to stuff everything inside your walls
Not Good.


As a counter point to 1.2: Overlapping Defenses, don't try to enclose everything within your walls. First off you will often break 1.2: Overlapping Defenses and 1.1: Defend your Defenses by trying to cover everything, but secondly it is just a waste of walls. Double thick walls are better than a massive single thick wall. 

1.4.1: What should I keep outside my walls?
Absolutely keep your builder huts, Laboratory, Barracks, and Spell Factory outside your walls. None of these matter if they get destroyed - no progress or resources are lost.

Next I would keep out Army camps, and Gold Mines and Elixir Collectors. Each of these has a consequence if they get attacked: Mines/Collectors get resources stolen (but only uncollected resources), and if an army camp dies all troops stationed in it die. Some people really like keeping Mines/Collectors inside - It depends on how often you play. If you do keep a few inside, make sure they are your highest level ones.


What does that leave? Town Hall, Defenses, Elixir Storage, Gold Storage. All of these should be inside your walls and as protected as possible. If you are at a stage in the game where you don't care about trophies, you can also kick your town hall outside the walls. You will be easy to defeat, but if you're only trying to protect your resources then the town hall takes up a lot of space.
