Archers and Elves and Damage

[ShuiMienLung]

"The +20% damage to archers means that archers do 20% more damage, not that you inflict more damage ON archers."

I've been meaning to ask about +% to damage. Are all pluses dealt with (and rounded) individually, or is there a total step ("this unit gets +X% to damage") and then it multiplies?

Specifically what brought this up: my KBTL game where I kept finding multiples of items, like 2x Sword of the Dragon Slayer and 2x Nephrit Belt. (Both of those say "+50% something", the first "attack" against enemy dragons, and the second "damage" done by my spider-y units.)

So is it done as:
base damage of the unit is 2-3
+50% is 1-1.5
rounded (if rounding happens) to +1 to +2
damage is 3-5
second +50% item is applied, with same rounding
so damage is now 4-7
(Discrete increments, rounding.)

OR with no rounding. In this case it would be:
base 2-3
+50 is 1-1.5 no rounding == 1-1
damage is 3-4
second +50% item is applied, with same rounding
so damage is now 4-5
(Discrete increments, no rounding)

OR is it done as "total of bonus damage (or attack) is +100%"
base 2-3
+100% == 2-3
total damage is now 4-6
(Total increment, rounding not relevant if total is 100%.)



And, obviously, 2-3 damage for the small spiders or skeleton archers is one extreme. Doubling the attack of EGD or red or black dragons on Ultrax leads to quite a bit of damage dished out.

In general, identical effects are added up before being applied. So if you equip an item giving +50% to all archers, and another giving +25% to all archers, the game just treats that as if you had equipped one item giving +75% to all archers.*

Note that "Attack" isn't the same as damage, by the way. The two are related, but only by a modestly complex equation.

*I know these items don't exist in an un-modded game. But I didn't feel like looking up actual items just for that example.

[ShuiMienLung]

Right, I was aware that +Atk <> +Dmg... except insofar as +100% Atk, when applied to Dragons (as I was referring to, there at the end) tended to crank any of them up into the low triple digits.
Bone: 43 + 100% == 86
EGD: 43 + 100% == 86
Red: 53 + 100% == 106
Blk: 56 + 100% == 112

86-112 attack of the creature, plus whatever actual Attack the Hero has (like for example a minimum of +10, simply for having both of the Dragon Slayer Swords equipped), and even a mage will be at 100 attack for the least of the dragons in his army.

That is GOING to be "higher Attack value than Defense of the target", leading to +3.33% damage per point. (The highest Defense I've seen on a hero (in KBTL) has been about +25 [on "normal" difficulty], so about 20 points over == +60% damage, roughly.)

I did start to see some of my Necromancers getting into the 120-Attack range, for the very late Tournament battles and some of the Boss battles (like the spider, I think), because he was laying waste to three and four and five unit stacks at a time with his area attack (at +6 Atk from Frenzy, per stack).
