This is one of two ways to get Templar dues, the other being Resurrection. The amount of dues gained varies with the difficulty of the dead mob. Animal corpses give one half or less of the dues of the corpse of a comparable sentient mob. Player corpses and clone corpses do not give any dues. Not all corpses can be buried this way. Only necessary for the first 1000 dues and for soloing. Parties will oft times tell you if you should be duesing corpses or not.
