Multiclassing - caraminden/anathema-roguelike GitHub Wiki

Unlike in some games, when the Player picks a Class at Character Creation, they are not locked into that decision for all subsequent Levels. If a Player is granted the Versatility Blessing, they are allowed to add an additional Class to the list of Classes they may invest their Levels into.

While there are no hard limits on how many Classes the Player many learn, it usually makes sense to try to focus on one or two additional Classes that complement the initial Class.
