I believe the only requirement is 80 slayer, and yes, kill the monster.
i dont thin u require 80 slayer.
its just for getting task.
what are the requirements to kill the things that drop these? sorry i dont know i just got on runescape and dont know much about this update
just found out the ones that drop the vine require 86 slayer
They require 86 slayer if you are assigned them as a task. You can free kill them no problem....
What this guy said.
In order to get them as a slayer task you need the required slayer level.
Unlike other slayer monsters though there are no required slayer levels to kill them.
Edit: seems like APs didn't have their info right...
RS Wiki for the win.
You DO need at least 86 slayer to kill the Gaurds and 91 for the Males.
The babies require only 80 slayer.
Lol @ what you quoted...
I do say 80, 86, and 91 slayer.
You must of quoted me right when I was editing.
