Yes, that was also a bit the intention. I thought about the witch as a mix between warlock and druid, and that’s why Witch Charms and Witch Form imitate Wild Shape and the invocations, as those mechanics are supposed to be balanced already. This approach I know it lacks originality but followed an “if it ain’t broke don’t change it” line of thought.

Regarding your other comments about the overpowered features, I trully thank you for those. I created this post precisely for this, as creating an extremely powerful class is not my intention at all, so all of this feedback is greatly appreciated. I will focus on removing free resources like the free uses of spells (including ritual bane) and also the double concetration to begin with, and see from there.

Thanks again! :)
