no.. it's what they often call isis bug / animus glitch.
basically, you put your animus in top of the cave, while you're inside the cave. then just use colon "," to send your animus to attack the mobs.
how to do this, ............ err... i can't explain it with words lol...
but the easy way is... use fly hack to go to the top of the cave, then summon your isis / hecate. then go back inside the cave again, your animus will stay in top of the cave and can attack the mobs without being hitted back. but you can only do this in certain spot because of animus attack range limitation.
this is the illustration :
Code:
animus
