Kinda pointless since you can just use an autoclicker, but this is one of my first scripts. This will also log how long it ran, how many alchs it did, how many levels it gained and will also stop when you run out of nature runes/items to alch.
Instructions: Just put nats/fire runes in your inventory or a fire staff and whatever item you would like to alch on the item slot right under the high lvl alchemy spell. (Slot #16 )
PS: I'm not responsible if you get banned using this ofc.
