I love the interactions between Minmax and Complains

I wonder what the light means. If it is part of a trap, it would be better set to Minmax (as it is now) because I think he'd be more likely to withstand any damage.
And if this is a trap, would a mute party be able to get through unharmed? The light didn't change colour until they started speaking did it?
It's possible that this is both a trap and a bonus, and Minmax is selected to be the main person targeted for anything the dungeon has.
(Also, have I put the date correct in the title? That's the date on the comic URL.)
