Loot is dropped when the monster is defeated. The loot that drops is random. Sometimes loot isn't dropped at all. This list is simply a pool of possible loot.

This monster does not drop loot.
Random spawns also apply to missions with floors that have geography similar to the relevant arcade area. The normal version of a monster can sometimes spawn instead of the status version in areas themed with a status, unless the spawn is guaranteed. See Gate Maps for details.
