The Deeper Well is the first map in Dungeon Defenders, and serves sort of like a tutorial for things to come (even though there is an actual tutorial). You only encounter the most basic of enemies here, like the Goblin, Dark Elf Archer and Orc.
You only have one crystal to defend on this map, and there are 5 points of entry for enemies, three on the bottom floor and two on the top. For the first few waves, you only have to worry about the enemies coming from the bottom, so it's best to set up some towers on the stairs, either leading down to the bottom floor or the steps leading up to the top, nearer the crystal.
