107.9% damage amplification. Tank with 100 armor and honor guard got 49.25% (47.78% if AoE) damage reduction, which is 0.75% (2.22% AoE) damage reduction while offense got 7.9% damage increase on all damage. The reduction effect from masteries decrease further the more you stack armor, while in the offense it is the other way around.
