This question is for gameplay purposes rather than lore purposes.
For example, while fighting Fabius I noticed he was hitting significantly harder than usual, and when he died he dropped a sword “of ruthlessness” with +24% damage to humans. Would the player character be affected by this, or is he/she immune to species-based damage bonuses?
Furthermore, since the player character is Taken, would %damage to Aetherial and Aether Corruptions deal more damage as well?
I never really thought about it until I encountered this weapon being used against me.
