You should closely approach the downed monster and say “Searching.” The monster’s player will likely give you any items the monster had. If your character has the “Harvest Game” ability from the Survival Skill, you can also call “Harvest Game” to see if there are any valuable parts of the creature that can be salvaged. Note that we do not send out very much “lewt” with monsters, or even most NPCs, so don’t expect the spoils of combat to be a driving economic force.
