Barbarossa's Lesson on Battle Calculations

Hi, apologies to those of you who have seen this before, but Kabam keep deleting my messages! Anyway, here is my current understanding of the battle system, and how it works.

To make sense of this, first we need to understand the combat troop attributes. These are as follows:-

RANGE - This is how far the troops can attack from. SPEED - This is how fast the troops move. ATTACK - This is how hard the troops hit. DEFENCE - This is how strong the troops are. LIFE - This is an indicator of how much damage the troops can take before they die. ACCURACY - This is a weird "unpublished" one, this is how good the troops aim is.

Battles start at the longest range of any of the troops involved (not including wall defences or possibly siege walls). In each "round" of battle, both sides attacks happen simultaneously, up to a maximum of 100 rounds.

In each "round", a troop can either ATTACK enemy troops if some are in range, or MOVE closer the distance of the SPEED attribute - it doesn't do both.

That's why range is so important. The high range troops effectively get "free shots" while the enemy troops are still too far away. That's why I always scout with range, I refer to it as giving my scouts longer arms.. Range also works for horses too, in fact all troop types. A lot of people overlook that..

Anyway, assuming your troops are in rage, let's see what happens during an attack. For this we need to know the troop attributes of both sides, which is only really available after the event unfortunately, by reading the small numbers on the battle reports!

Note - If multiple troop types are in range, the order of priority of attack appears loosely based on range, i.e. cats, balli and archers are targeted first, followed by hcav, cav and then other infantry types.

Calculation:-

First, we calculate DAMAGE. This is the effect one attackers troop has on a defender.

DAMAGE = (ATTACKERS ATTACK - DEFENDERS DEFENCE)

if DAMAGE < 0 then it becomes effectively 1 (which is very low).

Then we need to take into account LIFE (or health points) and accuracy, to find out how many attackers it takes to kill a single defender.

The magic formula is:-

NO. OF TROOPS = DEFENDERS LIFE / (DAMAGE * ACCURACY)

Which you then round up to whole numbers (can't have a partial troop!) to tell you how many attacking troops it takes to kill one defender.

(Note, all of the above are the actual VALUES, not the BUFF%, except accuracy which is a factor, e.g. 0.5% accuracy is actually an extra 0.5 on top of the base accuracy figure. Accuracy TR buff is capped at 1 I think.. I'm still not 100% sure how accuracy works, I wouldn't worry too much about accuracy for now...

Also for base Accuracy values I don't have a full list of, but the best I have found in this spreadsheet:-

https://docs.google.com/spreadsheet/ccc?key=0As_hS_NswVq_dDluYUVEVEVCNEN6dVpoa3FWMFRSZVE&hl=en_US#gid=0 )

Anyway, when you're attacking, you want the result of that formula to be as low as possible, to do that you need to get the DAMAGE figure as high as possible, so high LIFE, ATTACK and DEFENCE DEBUFF will help. When you're defending, the opposite is true, so you want high LIFE DEBUFF, high ATTACK debuff and high DEFENCE :)

Remember in a battle your attack and your defence happen at the same time (assuming all troops are in range of each other), so you need to decide what best suits you based on the enemy throne room.

Did I mention it's only really possible to work this out after the event from the reports? That's why it's often a good idea to let the first attack through before deciding what to do...

As an example, I'd like to use this battle :-

Battle at (xxx,xxx) Jan 30, 12:07 PM Report No: 107365906

Glory Gained: 3,773 Attackers (LowMightNinja) Knight Combat Skill: 255 Attack Boosted: 20% Defense Boosted: 20% Attack Results: Might Lost: 87,276 (563,262) undefined Troops Fought Survived Killed Heavy Cavalry 50,000 37,532 (12,468) Unit Stats: HP: 10,080 Atk: 3,211.46 Def: 2,879.961 Spd: 1,176 Rng: 112

Defenders (Stevan) Winner Knight Combat Skill: 255

Defense Results: Might Lost: 2,515,828 Rounds: 100 Troops Fought Survived Killed Heavy Cavalry ??? ??? (359,404) Battering Ram ??? ??? 0 Unit Stats: HP: 4,720 Atk: 2,572.5 Def: 2,817.495 Spd: 2,047.5 Rng: 60 HP: 16,000 Atk: 1,837.5 Def: 1,017 Spd: 327.6 Rng: 450

If you compare the HCAV troop stats between LowMightNinja and Stevan and plugging the values into the above formula, you can see it takes 12 of LowMightNinja's HCAV to kill one of Stevan's ... Damage is (3211.46 - 2817.495) = 393.965, so 4720/393.965 = 12 (rounded up to whole numbers, and ignoring accuracy)

However it takes 10080 of Stevan's HCAV to kill one of LowMightNinja's!!!! Damage is (2572.5 - 2879.951) < 0, so we use 1, so 10080/1 = 10080 (ignoring accuracy again)

As you can see, this battle didn't finish in 100 rounds, which is why troops survived on both side, but if Ninja had sent more troops (which he did on the next attack) he would have won easily (He was actually up against over 1.5 mill hcav here)

I hope this isn't too technical, if you have any questions don't hesitate to ask!

Cheers, Barb.
