TSHIRT SUPER MUNCHKIN MOMENTUS UNMASKING
If you are wearing the Momentous Unmasking shirt under another item of clothing, you may – once per game – dramatically reveal it when you encounter a Trap. You escape the Trap on a roll of 1-4. If you are wearing glasses, and dramatically remove them as well, you automatically escape the Trap!
Either Steve Jackson's or John Kovalic's autograph on the shirt lets you attempt to escape from two different traps. With both autographs, you may try three times!
Wearing two or more Munchkin shirts does NOT give you both bonuses. The one on the outside rules.
Use of the Cheat! card overrides Rule 4 and lets you benefit from two different shirts. (It doesn't matter which one is outside.)
But under no circumstance is there any bonus for MORE than two shirts at once, and players may never benefit from more than two shirts per game.
