there are 3 main ways to beat the game
1. slowly chip at the enemies health (Sisyphus's favorite strategy)
2. roll the enemies hp to low numbers like a normal person
3. "I cast 13 damage 18 times for 1 point, then tank 9 damage and heal 12 back. Finally, I finish them with a 1-point 80 damage" (personally my favorite out of the 3)
