[I] Zealot vs Zergling - Page 2

1. Reduction from splash zone(damage is multiplied by 0.25/0.5/1.0)
2. Armor amount reduction
3. Armor type reduction
If it's a protoss unit and:
a) Currently has no shields, just the armor type and amount of the unit are used.
b) It has shields, the shield upgrade amount is used and the armor type takes 100% from everything. If this attack depletes the shields, the leftover damage after depleting the shields is calculated again as in case a)

The minimum damage from an attack is 0.5 and this does not apply twice for the separate shield/hp calculations for protoss units.

Damage amount is rounded to 1/256.

Zealot - 2 attacks by 8 + 1 per upgrade

Scout Air - 2 attacks by 14 + 1 per upgrade

Goliath Air - 2 attacks by 10 + 2 per upgrade

Firebat - 3 attacks by 8 + 1 per upgrade, even burrowed lurkers can be hit by all 3 attacks, it just depends on the angle of attack(the amount shoed is hardcoded to be the damage of 2 of the attacks added up, but all three are upgraded and each deals 8 damage base)

Lurker - several attacks by 20 + 2 per upgrade, with the restriction that only 1 attack can hit a single unit and all of them have only 100% splash(the 50% and 25% areas are the same as the 100%, so a unit can't take partial damage from the lurker's attack). A bug can override this rule, this happens when the lurker dies the exact moment it attacks, then a unit can be hit by several of the attacks, it's easily noticable with full hp marines dying to a single lurker.

Valk - 8 attacks by 6 + 1 per upgrade, if there are multiple units in the 100% splash zone, only one will take 100% damage and the others will take 50%. The same aplies to corsairs.

Mutalisk bounces deal 1/3 less than the previous bounce, for example +1 damage muta against 3 targets with 1 armor will deal 10 - 1 = 9 on the first hit, 10 / 3 - 1 = 2.333...(rounded to the nearest 1/256) on the second hit and 10 / 9 - 1 = 0.111... upped to 0.5, which is the minimum damage, on the third hit.

Devourer spores increase damage from each attack by 1 per spore, this includes spell damage.

Not an unit attack, but since it affects attacks: Defensive matrix reduces attack damage to the minimum - 0.5, this includes spell damage. The total damage prevented is 250, but this does not acount the minimum damage inflicted or the unit's armor, so a zergling with 5 damage will perish the shield in 50 hits and still deal 25 damage, no matter the target's armor and the end effect will be 225 damage absorbed on a unit with 0 armor and even less on a unit with several points of armor(if the target has 5 armor, for example, the Defensive Matrix will NOT make any difference).

An exception to these 2 is the plague, which doesn't deal damage, but directly removes hp, so it doesn't interact with defensive matrix or acid spores(even if you change plague's attack type in the .dat files it doesn't change the spell's effect at all).

Nukes deal:
Against units/buildings with 750 or less total maximum HP + shields -> 500, 250, 125 explosive damage.
Against units/buildings with 750 or more total maximum HP + shields ->
2/3, 1/3, 1/6 of the total maximum HP + shields.
The three values are for the 100%, 50% and 25% splash zones ofc.

Burrowed units take only 100% damage splash. If they are in the 25% or 50% zone they will take no damage at all. You can test it even with a nuke - burrowed units near the end of the damage zone will take no damage at all, while unburrowed will.

Dark Swarm makes range units attack infront of the target, so units with no splash attack don't hit their target at all.

Reaver's scarab is a melee unit, so it doesn't effect it(Something interesting - if you press stop on a reaver, which has a scarab on the field, the scarab will explode dealing no damage).
Firebats deal most of their damage with their 100% splash, so they deal damage to burrowed units under swarm, they also deal line splash and fire exactly at the target, not infront of it.
Lurkers also can't really fire infront of their target, so they always hit and they deal all of their damage in 100% splash.
Tanks won't hit a burrowed lurker thay are aiming at, because the 100% damage zone does not reach the target(the radii on their 100% splash is 10, they normally hit a bit infront of their target and Dark Swarm makes them hit even more off)
High Archons as Siege Tanks can't hit the burrowed unit they are aiming at(under swarm), their 100% damage splash zone has a radii of 3 and they attack infront of their target, if they are too close to it, the actuall attack sprite will appear behind the archon or on top of it.
