Spellstrike

Type of Feat: Class
Prerequisite: Thrall of Graz'zt
At 6th level, a Thrall of Graz'zt can increase damage dealt when casting a spell on a target or targets threatened in melee (and thus distracted). The thrall can add half of their Spell Betrayal bonus (rounded down) to the damage dealt.

This bonus is +1d6 at 6th level, and +2d6 at 8th level. This ability continues to progress during epic levels following the half spell betrayal bonus rounded down rule.
