You could use 5 frost mages to kite in such a way

First Mage First Water Elemental


Second Water Elemental Second Mage


Third Mage Third Water Elemental

When the mob gets to that mage, have it ice block and it will go to 2nd mage if you only cast with 1 at a time. Tedious but you could continue to do so for 10 ice blocks + permafrost
