Something I came across by accident:
When the mind runes of my splasher were used, it didn't log out but instead started switching between spellbook and inventory, 4 times per second. After 30 seconds I stopped it manually. The night after I tried it again and exactly the same happend.
Also, after a relog, its not targeting enemies which are free to attack, sometimes it tries to attack a spider 30 times before getting a free one.
Other than that, works like a charm. I can even splash 12 hrs a day on fresh accounts, which is pretty awesome
