Spellspire

In order to unlock the dungeon levels, you must first complete all 100 levels in the tower. Then you can access your current dungeon level by pressing . There is no level select with in the dungeon- you only have access to the current level.

The dungeon is structured differently than the tower. Levels are endless and you play until you die. On each level, you are given three tasks to complete. Complete all three to earn a trophy and get three new tasks. You must earn five trophies to advance to the next level.

Tasks requirements are things like "kill 4 enemies with palindromes," "kill 12 enemies in one run," "find 12,000 gold," etc. Progress is carried across each run unless noted otherwise on the task (so you could kill one enemy with a palindrome, then die, then repeat three times for example).

Reach level 10 in the dungeon and this achievement will pop.
