Ok i'm quite sure noone knows it 100% but i would like to know what you think.
SPIKE TRAP
With set them up i get 25% bonus damage but i don't understand if that 25% is added to the base 300% (325%) or if it's 25% of 300% (making 375% total)
ELEMENTAL MINES
Description says 50% weapon damage. So if i have 150 damage dagger it's 75. let's say ii have 50% attack. Let's say it's critical and i have 100% bonus critical damage,it means i do 150% total bonus damage. and 75x250%=187.5
Ok now i saw many mines doing more than 2000 damage....how is it possible?
With the disclaimer that I never used Spike Trap, I believe damage bonuses are additive unless otherwise noted. So 325% is what I would expect.
For the Elemental Mine calculation, we need the damage formula:
final_damage = (base_damage * rand(0.95 to 1.05) - armor * (1 - armor_penetration))
* (ability_multiplier)
* (1 + critical_damage_bonus + flanking_bonus)
* (1 + attack_bonus + damage_multiplier + type_bonus)
* (1 - magic_resistance)http://forum.bioware...mbat-mechanics/"X% of weapon damage" is the ability_multiplier, since you can see that it multiplies directly into the base_damage, usually resulting in some fraction of base damage.
Then you multiply that value into to base damage, along with other buffs/debuffs. So if your base damage is 150, your attack is 50% and 100% crit damage, your expected damage with an elemental mine is:
base_damage = 150
ability_multiplier = 50% = 0.50
critical_damage_bonus = 100% = 1.0 (assuming a crit hit)
attack_bonus = 50% = 0.50
expected_damage = (150)(0.50)(1 + 1.0)(1 + 0.50) = (150)(0.50)(2)(1.5) = 225
If you are seeing 2000 crit damage numbers for a single mine, you probably have some other buffs going on. For example, is the target vulnerable to fire and it's a fire mine? Do you have other passives that increase combat damage value or crit damage? Are you using the One Shot upgrade toggle, which basically adds all the damage of the smaller mines into one large one?
