Roll of the Necromancer

Defeat the necromancer by using your sword!However, he's way too durable and every time you defeat him he comes back stronger, how do we deal with that? Use the power of the dice roll to increase your damage. Hitting consecutive rolls is harder each time but increases the damage of your next attack further and further. Be careful though, if you get hit all your stored rolls are lost and you must start over. Good luck! And don't forget that luck is a skill!
