			However, live testing confirms that standard Damage Reduction debuffs have not been fully migrated to this new system. Currently, Damage Reductions (such as {{ItemIcon\|Inhibitor}} or {{AbilityIcon\|Fire Scarabs}}) simply act as negative Additive Amps. This means they add directly together with other additive amps (positive or negative) rather than multiplying against each other.

LVL: Did some testing and think I figured out how damage amp/reduction works. Made some changes to the examples and fixed up some other stuff and added an explanation for weird damage result with bloodscent.
