Make sure that the cult leaders or high priest offer blessings and salutations "In the name of the barrel, and of the foam, and of the golden nectar" or something like that.
My celestial warlock does that. He's a dwarf who likes beer and serves an Emyprean of such things (the vine, spirits, beer, etc) in our Curse of Strahd campaign. I have a small macro in roll20 that I push to put that blessing/greeting into the chat.
Also: love Bubba Yaga.
