Any other building interior

Any other building interior is an entry in the Where enemies appear database, listed under Building.

Each table has 20 slots, weakest first. The game picks a slot near your level: roughly a level-3 to level+3 band, sometimes the first level+1 or level+2 slots, and for a high level the last six slots. The slot a monster sits in is therefore how strong a player it is meant for. Towns spawn nothing by day.
