Dark Law: Meaning of Death/Monsters

"Spoils" are items received upon searching an enemy's corpse. Generally speaking you can only do this if you defeated the enemy in Dungeon Mode, and it's random whether you receive the spoils or not.

The "status" data is based on examination of the ROM data. Bear in mind that this process is incomplete, so a blank space doesn't necessarily mean that an enemy causes no status effect.

No value for experience is given. This is because experience seems to be an attribute of groups of monsters, not of the monsters themselves. For example, a group of five Slimes gives you 100 exp and one of three Oak Jellies gives you 90 exp. Based on that, you might think that one of four Slimes and one Oak Jelly would give you 110 exp - but it actually gives you 200.
