Most interesting tactic, and very imaginative, if I might add. However, that pretty much forces you to go on a kiting spree, because you'll need to start around lvl 20 or so to make good use of the spells you listed with a warrior, because you will be hard pressed to delve deep into the magic tree. In addition to that, you will need a good supply of mana to achieve that goal. Time back is 30, Sacrifice is 20... If you don't have any good means of restoring the mana (like mana accelerator, because concentration is way too deep in the magic tree and you need distortion lvl 2 and chaos lvl 1 at least), you may be stuck at ground zero if you don't have enough runes.
