Catched fishes carry trophy data like location and date of catch and also the name of whom has catched the fish. It would be nice when at least the skulls carries they same data. The name of whom has won the fight may be estimated by the killing blow (last hit) or whoever deals the most damage. The size value may be a difficulty value either taken from adventure level divided trough 10 (or 12) or the adventure level difference between the victim and the winner. (can also be negative) This addition maybe also be used for a player driven bounty system. Since one can see this is a fresh skull.
