For the next roll of a d20, the victim of this curse automatically gets a natural "1".

If this spell is cast at a higher level spell slot, the victim gets an additional natural "1" for each concurrent d20 roll after the first, for each level of spell slot used over 3. So, for a 4th level spell slot, the victim gets two natural 1s in a row. For a 5th level spell slot, 3 natural ones in a row, and so forth.

If this spell is cast on a character actually being played by Wil Wheaton, there is an instantaneous rip in the space time continuum and everyone within 30' is sucked into the void and never seen again.
