Quest: Parched gnome priest on Eastern Tundra
Important prep choices: Binlor, Magnet: Defend (was PISSORF)
Subdungeons: Glenrick and the PISSORF Ice Troll
Keyword: Efficency ^^
Essentially I went for a Stone Skin + Stone X (might on wall destruction one, form? i just used it and I still cant remember it's name). I worshiped Binlor first (after using the Slayer Wand and the STR potion), PISSORFFED monsters into walls, then used ENDISWAL in subdungeons mostly, untill I got both the Stone Soup and the Might boon. Then went Drac, converted all the useless health potions and grabbed a hit of sanguine. Got a few levels and sanguine piety, then converted to Mysterea. Got Refresment for all the extra glyphs (2 from BINLOR, 1 from subdungeon). Had to resort to shennanigans to get my piety up to 25 with no potions and no exploration (shennanignas invloved the use of refreshment and munching all the popcorn, go efficency, whoop!). I desecrated Drac to get to 50, joined Binlor again. I had low Binlor piety, and noticed I still had unreachable exploration and LEMISI lying right there. And I've just left Mysterea, eficceny - 110%! I used the remaining glyphs for mana needed to endiswall for both piety and resistant hits on Blah Blah, then went straight into a Stone Skin spike. Testing it was my intention anyway... It leveled Blah Blah with a parched gnome priest who had no fuel except about 45 Binlor piety, a bunch of walls, a scadenfraude and a few useless glyphs (no dmg ones apart from BURNDAYRAZ against a retaliate fireball boss, go me).
Net result: victory
Well, Eastern Thundra isn't all that difficult, but the Stone Skin spike is probably really strong. If I wasn't trying to be clever and go god hopping, I could've done it all in a less convoluted fashion. In retrospect it was a blind idiot run, with an easy boss run over by a piety spike despite "funniest home video" levels of missplay on practicaly every other click. Fun, though. Got Miser on top of it all, and cheeky which I didn't have before ^^.
EDIT: Oh, and I forgot, i did prep a pair of dodgestep potions, or I would've needed more piety for the spike. There was a platemail in there too, but it wasn't too significant overall.
