I suddenly had an idea for a Ritual Device. What about having a pact with Dionysus, God of wine and merrymaking? It's said that when he's at a celebration and dances, he frees others from negative feelings.
So I was thinking, if someone made a pact with Dionysus, he could use that power to 'power up' those around him. He's sort of like a support-type character. Of course, he needs to be celebrating and/or drinking any form of alcohol.
What do you guys think?
