Patches can grant the following boons. To my knowledge, each boon has a equal chance of occurring with each level up:
+3 Health
+3 Gold
+5% Attack Bonus
+1 Mana
+4% Physical and Magical Resistance
He also inflicts one of these curses with each level up:
Mana Burn
Poison
Teleport
Grid Reveal
On long runs, you're usually hoping for the resistance boons. Mana Burn is the most consistently dangerous curse. Teleport and Grid Reveal can range anywhere from slightly helpful to game ending.
