NASTY VARIANT
All of the usual rules apply, with the following exceptions:
• You can use a magic spell at any time — even on another player’s turn! — but only one per action (instead of one per turn.
However, you may use that one magic spell multiple times at once if you spend enough potion bottles.
Example: If you spend 4 full potion bottles, you could cast “Move a Wizard” twice.
• You can use magic spells for or against anyone you choose.
• If multiple players wish to cast spells at the same time, go in turn order, starting with the current player.
• You can cast the spell before, during, or after the action (your choice); however, it cannot undo an action that is complete.
If your spell prevents completion of a movement card, the card stays on the discard pile, and the action ends incomplete.
