Ok, I know the basics of damage reduction:
Say if I have Inquisitor with aura of censure and horn of gandarr, those will not stack since they both read “reduced target’s … damage by x%” and only the largest debuff will be applied.
But what about “y% less damage taken from” racials like on Word of renewal
will they stack additive or multiplicative with the “reduced target’s … damage by x%” debuff?
