Bug with Radiant Aurite: Double ability for Mudgill!
I gave Mudgill the Radiant Aurite and they got Feeding Frenzy two times! They already had that ability. I did so to get Chunk and Hunter's Quarry. Don't know why Feeding Frenzy triggered again. It apparently counts for the "Nature" synergy count, so I don't think it's just a visual glitch.
