This has been corrected.

Basically what was happening was, when triggering, the game getting 10% of the damage dealt and treating it as bonus damage resistance. So if you took 200 damage, it'd be 10%, which is 20. However, the way it was actually calculating that was as bonus damage resistance percentages, so it'd be checked again as 20% of the damage, bringing the actual reduction to 40 damage (in this instance).
