When you forge a pact with the Spirits of the Land, the Elements and the primal Beastkings you may take this move the next time you level up:
Compendium Class Warden
Inspired by my favorite 4e Class, the transforming Warden.
The most extensive thing I wrote for DW until now but i had lot of fun with this, writing up Guardian Forms really is cool.
Giving you just 4 forms might be a bit few but this means you have to choose. You can also work with your GM on what kinds of things you have to do for the spirits so that they grant you additional forms.
They tend to be a bit strong i think but the 7-9 effect on them will change up the battlefield and situation pretty good. You will have to figure out how long you will want to stay in a chosen form and reap it’s passive benefits and when to unleash PRIMAL POWER! I like that.
I am not sure if it is cool to just give them a limited multiclass into Druid but i felt those are the best moves for communing with the primal spirits.
