@Ethan Elliot Don't forget about Killing a new kind of monsters, When you Kill a New monster you get XP equivalent to that monster, sometimes you get 1 for a new monster sometimes 2 or 3 XP, the "Mutations" or "Variants" also give new XP like the Goblin Archer or a Goblin Warrior (maybe im wrong about the mutations)
