Here is a very mild baked brie: https://rpg.stackexchange.com/questions/134677/can-you-awaken-a-sentinel-raven-raven-queen-patron 

It's got a nice blend of poor or incomplete/not fully baked wording from Unearthed Arcana that allows a class feature to be more powerful than likely intended.

This cheese may not have fully melted when served.
