Your touch attacks become exceptionally deadly by sacrificing accuracy for magical strength.
Prerequisites: Int 13 or Wis 13 or Cha 13.
Benefit
You can choose to take a –1 penalty on all spell and supernatural touch attack rolls (including power rods and power staves, but not animated dolls) to gain a +1 bonus on all spell and supernatural touch damage rolls. When your caster level reaches 4th, and every 4 caster levels thereafter, the penalty increases by –1 and the bonus to damage increases by +1.
You must choose to use this feat before making a touch attack roll, and its effects last until your next turn. The bonus damage does not apply to effects that do not deal hit-point (HP) damage.
