Residual Rebound

(Unearthed Arcana, page 94, DnD 3.5)

[Spelltouched]

Sometimes spells cast at you rebound on the caster instead.

Prerequisite

Exposure to spell resistance or spell turning spell

Benefit

If you roll a natural 20 on a save against a targeted spell, it turns back on the caster as if affected by a spell turning spell. Unlike spell turning, however, the Residual Rebound feat potentially functions against touch range spells as well. Residual Rebound only works on targeted spells that allow a saving throw, so a fireball won't rebound, nor will a power word stun.
