So, as usual, right after I finish complaining about the challenge I manage to beat it. Also as usual I just want to point out that just because I beat it that doesn't make it balanced.
Strategy
Head towards where you estimate the furthest part of the level is. Don't go diagonally though, skirt the edges of the level. If you find a long corridor that's like 3-4 blocks away from the edge of the level then you know where to head.
You need to get damage up to 6 and health up to 11 (IIRC) before you can fight a level 2. Then attack, health pot, mana pot, attack, weytwut, attack. Now you're level 2.
To fight level 3s you need to get 12/26 damage/health or 13/24 either will let you go attack, regen a few tiles, attack, weytwut, attack.
From then on you should be able to do the attack, regen, attack, weytwut, attack dance. Throwing in ENDISWALs at higher levels.
I instaconverted the GETINDARE glyph but kept all the others. Use ENDISWALL on thick edges to get access to dark tiles you wouldn't have been able to while you are charging your resist. Use IMAWAL on level 9s. Save one if you want but you probably won't kill any of them. Before the boss I converted all of my glyphs except BURNDAYRAZ. Then I just attacked when I had health and cast BURNDAYRAZ when I had mana, I got a level up to 8 during the fight too.


Balanced dagger looks interesting.
