about the script you should talk directly to him. -edit- if it's paid, aks support to him,
if it's free, ask him, if you don't get help send me the script by email and I'll check it for you. but ask for him first, check the script's thread about feedbacks etc.
about ring, just add 2 action waypoints (if y u don't know how I'll explain, just tell me).
first, on entrace:
moveitems("dwarven ring", "all", "ring", 1)
second after leaving .but you'll be drunk after removing it, I would keep the ring always equiped, since it's cheap and by the time the drunkness is gone, you'll be almost back to the hunt, anyway, he it goes :
local RingBp = MainBP
RingUse = ring
