Each attack you make is made with the tactical precision of surgeon’s scalpel, each attack you miss is merely a faint. You gain the two following features:
Devastate. When you hit an enemy with a melee weapon you are proficient with, you can choose to gain -1 penalty to your next attack roll and +2 damage to your next damage roll. Once you choose to use this feature it stacks with every successful attack, to a maximum of -5 to hit and +10 damage.
When you miss an attack you lose all bonuses and penalties provided by this feature.
Opening. When you miss an attack roll, with a melee weapon you are proficient with, gain +1 to your next melee attack roll. If you consistently miss attack rolls this bonus will continue to rise until you reach +5 to hit. All bonuses from this feature are lost when you land a hit.
