Melee Power

Overview
This attribute introduced in Update 23 is similar in effect to Spell Power, and increases straight weapon damage in addition to certain static effects from enhancements. Melee Power is gained from certain enhancements, some melee Epic Destinies, some feats, and future loot. This rating increases melee attacks by the following formula: (100+Rating)/100; x percentage increase. Example, A character with 20 melee power that does 50 damage with a weapon will do a total of 60 damage. Melee Power is applied to Sneak Attack damage.

Formula for negative power: 100 / (100 - Power).
 * -50 Melee Power means you deal 100 / (100 - -50) = 100 / (100+50) = 100/150, or 2/3rd, or 66% damage
 * -100 Melee Power means you deal half damage, etc.
