Clank!: The Mummy's Curse

You can fight and defeat the Mummy only when its marker is in the same zone as your current room. The Mummy is not discarded after being defeated. (Rulebook, p. 2)

With two Swords, you gain 4 gold and take a Curse. With three Swords, you remove half your Curses, rounded up. (Rulebook, p. 2)

If the Mummy moves to a different zone, every player in a room in its new zone takes a Curse. Players do not take Curses if the Mummy remains in the same zone. (Rulebook, pp. 2–3)

Yes. You can defeat the Mummy more than once during your turn, although you may need to follow it to another zone to do so. (Rulebook, p. 2)

No. Taking an artifact is an action during your turn, so you may take it on a later turn as long as you are still in the room. (Rulebook, p. 4)

Each Curse remaining with you at the end of the game reduces your score by 2 points. You may remove Curses from yourself when an effect allows it, but never from an opponent. (Rulebook, p. 2)
