Hey there I have good news and bad news.
Bad news is I just found a bug for superior npcs, apparently the script just attacks any superior npc nearby which is very bad, but it's an easy fix. Good news is that the gargoyles update has been submitted for v282.0 (which'll auto-update within a couple hours). and I'll be adding the superior bugfix onto that too.
So once 282.0 goes live, slayer npcs should be much safer to bot
EDIT:
Also guys a quick update on the prayer altar feature - I know I promised a couple days ago but still working on this. Can't release until everything's perfect, I will try get this feature done before monday latest. Again my apologies!
