Interfering in combat

[antee]

Hello!

Recently we have big discussing about using "FriendShip Potion", "Monsters are busy", "Out to lunch" and etc.

Okay, two situations:
1) Player A is fighting with monster, he uses a pollymorph potion and defeat it... could player B play friendship potion (or out to lunch, or something like that), to prevenet player A taking treasures?

2) Player A is fighting with 2 or more monsters and he gets rid of one of them with pollymorph or wizard power... player B uses friendship/out to lunch and etc... would player A get treasures for defeated monster?

Thanks for ur help!
