The sticky Thread should be used for quest requests.
Here is a quest that should do the thing you want:
Code:
quest pvpkills begin
state start begin
when kill with npc.is_pc() and pc.get_level() >= 30 begin
local items = {--vnum, count
{27001, 200},
{180, 1},
{187, 1}
}
if number(1, 100) <= xx then
local rand = number(1, table.getn(items))
pc.give_item2(items[rand][1], items[rand][2])
end
end
end
end
replace "xx" with the percentage chance to drop anything (for example if you replace xx with 50 there will be a 50% chance of getting one of the items in the list)
