Damage Formula
(((Weapon Damage * Impact Zone Bonus * Combo Bonus * (1 + Power Bonus)) + Additional Physical Damage) * (1 + Hit Location Bonus) * ((1 - (Damage Reduction * (1 - Penetration))) * (1 - Projectile Reduction)) + True Damage
Attribute Bonus Ratio
- "Attribute Bonus Ratio" is a hidden modifier present on a variety of spells, items, and skills. It will modify any sources of personal bonus damage/healing/shields/whatever else, based on its multiplier.
What does this include?
- Power Bonus (Magical and Physical)
- Magical Damage (From Spellbooks, Staves, and Crystal Balls)
- Divine Strike's special Physical Damage buff
- Additional Damage (Magical and Physical)
- True Damage (Magical and Physical)
- Weapon Damage (There is currently nothing implemented in the game with Attribute Bonus Ratio that can also benefit from standard Weapon Damage)
- Magical Healing
What does this not include?
- Location Bonus (Headshots, Limbs)
- Enemy Damage Reduction
- Projectile Reduction
- Here's an example using default Wizard's Ice Bolt. Ice Bolt has a base damage of 30, the default Magic Staff grants 5 Magical Damage, and Wizard's default Magic Power Bonus is 15%. This spell also benefits from Headshot Multiplier, which is 1.5x.
- Without Attribute Bonus Ratio, the damage calculation would look as follows:
( 30 + 5 ) * (1 + 0.15) * 1.5 = 60.375
- However, with Attribute Bonus Ratio of 50%, we must halve the +5 Magical Damage and the 15% Magic Power Bonus. Headshot multiplier is unaffected.
( 30 + 2.5 ) * (1 + 0.075) * 1.5 = 52.4063
