Drawngeon: Dungeons of Ink And Paper (EP)

The Wizard is a tricky class to use, but can be a bit foolproof since you can keep your distance from enemies as long as you unlock the fire spell. Most enemies, and luckily the trickiest ones in the game in the final dungeon, won't move unless you do, so you can shoot fire spells until they die and recharge your mana to kill them effortlessly. Put most of your points into Intelligence for more mana.
