Towers of Babble: How to Unlock All 20 Secret Classes

Towers of Babble

Towers of Babble has 20 secret classes. A tower turns into one when its stats reach that class’s requirements, and each class gives the tower a special effect.

The game shows a class’s criteria and description only after you unlock it. You can then find it in the pause menu under Secret Classes. Before your first unlock, you need to know which stats to build toward.
