Concentration [Wis -2] (1 slot)
This proficiency allows spellcasters to maintain their spellcasting even after suffering damage. If the caster only suffers 2 or less hit points of damage before he is finished casting spells then he is totally capable of finishing his spell with a proficiency check. Otherwise the caster has another +1% bonus per level of maintaining and casting a spell while being injured. This raises the percentage chance to 3% per level of casting any spell after suffering damage in the round. This damage cannot exceed half the caster's total hit points, however, or the spell is lost as normal.
