soz was ment to post this for u the over day but forgot but here it is :P.
go into customcommands and type @killpet
then go into market_def and go into Qfunction-0 in here paste this
[@killpet]
#if
#act
killslave
LineMsg 6 "Your pet has been killed"
BREAK
now restart m2 and type @killpet ingame this will allow anyone to kill there pets ingame.
if you want u can copy it and put @killpets aswell then going into customcommands and do the same so if someone type @killpet or @killpets it will do the same job just change what it says "Your pet has been killed" etc.
