Feat: Return Unto Runes

Frequency once per 10 minutes

Trigger An enemy targets you with a spell attack or other magical attack against your AC.

---

You attempt to deconstruct an incoming spell into its individual magical components, storing them temporarily as a rune. You gain a +4 circumstance bonus to AC against the triggering attack. If the attack misses, the spell becomes sealed in a rune, which floats around you. Until the end of your next turn, you can Trace this Rune onto a creature as normal. This rune doesn't have an effect until it's invoked. When the rune is invoked, the rune-bearer is affected by the spell or magical attack captured in the rune. Make a check, using your class DC – 10 as the modifier against the rune-bearer's AC to determine the effects.
