I've spotted it is possible to have either a spar, or a battle between at least two people in a bdp floor, then end the battle without finishing it off, and have it spawn a monster.

I don't know the exact details myself (whether it was a spar, battle, end turn or flee), but the result is clear- It allows one to spawn a monster in the end floor after it was cleared up to kill, and then go for the boss for a full floor clear bonus with ease.

I'm... Unsure if this is a bug exploit or not, but leaving that report here for later so other people can test it out further- Can't really PVP with myself.
