Does Paelleall's Wrath of the Volcano ability affect Heroes on her tile and the Entrance Tile?
It looks like you cannot get any more definitive than the designer himself, Mr. Bistro:

Q: Is Paelleall's Wrath of the Volcano ability include hitting all other heroes on Paelleall's current tile, and any figures standing on the Entrance Tile as well? I would assume that it does, but it isn't clear to me.
A: Yes, that is the intent. Every tile in the path is hit.
