Does the % to Reduce X damage from shields stack with regular damage reduction? I know say the ring of mastery reduc does not stack with the Shroud reduc for example, but because its a % chance to reduce I'm wondering if it would. Or at the very least say if its % to reduce 200 Damage and always 50 damage, would the 50 DMG stick on the times that the % to reduce doesn't, then when the % goes off it takes precedence over the straight up reduction?
