1. Racial Damage on weapon (including weapon components and augments) will be calculated twice/have double effect for DoT. (Maybe only for Projectile Burst, Projectile Fan and Projectile Ring skills.)
Testing process:
Here’s a Chthonic Dummy. My weapon has 10% chthonic damage from Imbued Silver.
I used default attack hitting dummy, flat damage = 566*(1+10%) = 623, correct.
I used PB hitting dummy, bleeding damage = 764*(1+10%) = 840, incorrect.
917/764=120%.After more testing, I drew the conclusion: for PB, Racial Damage on main-hand weapon would be calculated twice, while Racial Damage on off-hand weapon would not be counted in.
I tested several weapons and affixes. Crystallum, Basilisk Claw, Runecaster’s, Of Insanity, etc. They all had this bug.
Edit. I might make a mistake, it seemed to be an issue of Projectile Burst, Projectile Fan and Projectile Ring templates. DoT from Savagery, PS, ABB and SS didn’t gain double/twice racial benefit. DoT from Siegebreaker, Shar’Zul and Scorpion (devotion proc) did.
2. Racial Damage on Relics (including their base stats as well as Completion Bonus) is invalid/ineffective.
The testing process was similar. Both parts in the following picture were invalid/ineffective. Damage remained unchanged whether I equiped relic or not. And invalid/ineffective for both flat damage and DoT.
I also tested several relics. Oblivion, Scourge and Blademaster. They all had this bug.
