Your shadowy illusions are more potent.
Benefit(s): When casting greater shadow conjuration, greater shadow evocation, shadow conjuration, or shadow evocation (and, at the GM’s discretion, any similar spell with the shadow descriptor that mimics a spell of another school), that spell is 20% more real than normal.
Level Increase: +1 (a solid shadows spell uses up a spell slot 1 level higher than the spell’s actual level.)
