Will of the Infernal - Whenever you roll a d20,
you may pay X life where X is half the
result rounded up. If you do, double the result.
If the result would be greater then 20, it becomes
20 instead.
Whenever you roll more than half
a die's highest value, you may draw a card
and deal 1 damage to any target.
