After Xom trying and failing to kill me early game (thanks to the OP searing ray), the mid and late game were basically a breeze. Xom was mostly an inconvenience, summoning “helpful” imps which basically got in the way of my spells or teleporting me around, but they did give me a +8 int -2 str/dex mutation which was quite helpful in the end game.
My main weapons were
early game: Searing ray
early mid: Olgrebs, fulminant, searing
later mid: arcjolt + above
late game: plasma beam, orb of electricity
extended: plasma and chain lightning, Maxwell’s capacitive coupling
Cigotuvi’s Embrace (arty leather armour) is awesome. I had it up to like +40 in V5. It fell off somewhat in extended, but was surprisingly useful in Tomb, thanks to death scarabs having corpses.
Crystal Ball of Wucad Mu is nice.
Chain Lightning is probably OP. Unlike most spells which have strengths and weaknesses which encourage you to use a wide array of spells, Chain Lightning is all strengths and no weaknesses
Maxwell’s was used to take out most of the bosses, and also put in a lot of work in Dis, thanks to most of the enemies being resistant to everything.
I pumped up shapeshifting solely to get death form for tomb, and tomb was no trouble.
I learned ignition for tomb. I could’ve sworn that mummies had fire vulnerability. But I guess that was removed at some point? Anyways, I still used it a few times.
