Fight kiln Wave 35 - how i take 0 damage on any account type

This was just uploaded because a friend said he was unsure on how to do wave 35 safely which is why i didn't edit it or add commentary. Basically you stand in the south west corner , use the crystal and kill the ranger. then proceed to run east - north under jad and finally west to the north side of the rock where you are protected from the mage+meleer
