Munchkin Cthulhu - Solar Eclipse card effect and participants in combat

[MunchkinMan]

I don't think we've ever treated that word differently, but only those fighting the Monsters are considered participants in the combat. Helping either side, adding Monsters, etc. does not make one a participant in the combat from the game's rules perspective.

I'm not sure why the card needs to be considered any more detrimental than it is, as it removes the choice the players have in what Treasure they get. Often, negotiations over who will help involve order of choice.
