You heard me.
I mean a miniscule amount of loot and no materials. And, this loot would scale down as the monsters kept respawning, so it wouldn't technically be infinite loot. No, this doesn't mean mini-royals would drop loot.
The reason why this change wouldn't wreck the game is because play is unlimited. I could get crowns faster by skipping the spawn pads, but then I would get something for killing the stuff that comes off them. (Thinking of the final battle before Roarmulous Twins.)
