Trickington, God of Tricks

At the beginning of your turn, prepare a trick. When an event that could trigger one of your tricks occurs, you may activate your trick by stating its name but you may lie. The affected Wizard must decide if you're bluffing.
•If they believe you, activate the trick as
though it was the one you stated.
•If they call you bluffing and you're not, activate the trick and deal 2d20 damage to them
•If they call you bluffing and you are, discard the trick.
