Domain: Trickery/Illusion

Effect: 

Once per battle, as a quick action when you are engaged with an enemy, roll a d20 (your 'trick die').

As a free action before the start of your next turn, give your trick die to a nearby ally or enemy who is about to make an attack roll. The trick die result becomes the natural result of their roll instead.

Invocation of Trickery/Illusion: This battle, attacks against you by enemies that moved to engage you during their turn miss on natural odd rolls.

Champion Feat: 

Your trick die can be used for any one d20 roll, not just an attack.

Epic Feat: 

You get another trick die roll to use each battle the first time the escalation die reaches 3+.
