i just noticed one thing about the looter:
if the first item of the body is gold and you don't have enough cap or space in the backpack for loot it it won't try to loot any other items.
for example im hunting with my 40 mage in earth elementals, and i just bring 1 backpack because i don't want it to loot more than 2k for each 110 manas. Once the backpack is full it wont loot any lump of earth because the first item of the body is usually gold.
nothing else than that
