With my necro I could last about 6 rounds against most warriors at that level. You can get a pretty nice +hp set just by paying heroes for good but non-limited items.

Then you can get a couple of wands and see about surprising the warrior when he's hurt.

If he's a village ap and anything other than human-size, you can remove his ability to permalag you and pretty much ensure your escape.

For example:
- get yourself a +hp suit. Gold is usually enough to accomplish this. Lots of heroes will kill a mob for you in return for 20 gold, provided you're not asking them to put themselves at risk.
- get yourself a way to minimise the chances of permalag (e.g. reduce, enlarge)
- remove other obvious sources from the lag equation unless you want to be lagged. For example, if you want to zap said rager with a wand, you might not want to be flying, but most (not all) ragers will trip in such a way that you can still zap them every 2 rounds, hence their trip is accomplishing very little.
- don't fight at a place where you might find it hard to flee. i.e. don't fight at the massive giant or the entrance to a guild.
- find some wands and get hold of them. They are out there. I'm not talking sleeks, but rather some limited ones. If you have to, pay another high level mage for some. There's a good chance they have other wands they can use so don't mind chucking you the stuff they used back when they were low level, in return for some gold.

If you assume that the task is impossible, I would argue that you don't have the right mentality for scion, which is, perhaps, why the cabal leader is doing this kind of induction process.
