Looting:
Looting creatures will usually yield treasure, or money, or merely mundane items. That is according to the luck of the roll.
A non-sentient creature will usually not have treasure on its person, be fealthough it may be feeding on a fresh kill that has treasure of its own. It will take its kill to its lair, devour it, and leave the items to rot. This is up to the Game Master.
Finding the den of a creature usually involves tracking, unless circomstances permit an easy trail to follow (i.e., snowfall, muddy tracks from a rain storm, or heavy inpacts from the creature).
The Game Master will always decide how a lair or den is found by adventurers. He or she will set the circomstances and then see how it playes out.
Special:
If one of your group falls in combat, and is looted by the members of the adventuring group, there will be a 30% chance of the deceased coming back as a phantom and haunting the ones who took his or her items. If the body is not properly buried with respect, the % chance will increase to 50%. When a comrade is looted and discarded, this often times creates a deep, dark enmity within the deceased. It's rage will know no bounds until it is appeased, or destroyed. Use the creature Phantom in the Creature's Book for this. Depending on the power of the characer in life, the dead will be a Lesser, Common, or Greater Phantom. The deceased will wish the worst against the ones who so disrespectfully desicrated his or her body. It will never stop in its path of revenge until all are destroyed (either in mind, spirit, or body).
