How you doing, thread, hope at least someone is having fun playing Crawl, because I most certainly am not.
12 runes on my current GrEE, and what was the most fun I've had in a 3-rune game turned into the worst post-endgame run I have ever experienced.
Tons upon tons of pan levels without an exit, a holy pan level [first time running into one of these - felt the bizarre need to clear it fully and let me tell you it is proper bollocks], had to flee from Cerebov's level without so much as smacking him on the gob as I ran out of food [!?!?] clearing the endlessly respawning hordes of balrugs - only way out was through the abyss, where I quaffed absolutely all of my potions as I was constantly starving, surviving on the precious few pears and apples scattered across the abyss [Thanks, Fedhas!]. If I hadn't hybridized I would've starved, as I could at least beat demons over the head with my cane in the Abyss, instead of just quitely starving away.
I finally escaped the abyss, and went into the hells, going for Cocytus first. It took me more than 10 tries to kill Antaeus, then it took me about seven standard aeons to even get to Ereshkigal and Dispater, but I killed them both within two or so attempts.
I guess my build was really not optimal for post-endgame, and I'm not even a good player, so I kind of need overpowered builds to carry me. I started my build by only training Spellcasting, Earth and Conjurations until Shatter, then transitioned into a melee/earth hybrid with staff of earth. This was by far the most fun I've had pre-endgame, but Shatter is horrible for post-endgame AOE [tons of flying stuff] and Earth doesn't have anything else, and I stubbornly refused to branch out because I felt I should be strong enough.
Well I am not. The endlessly respawning waves in the hells are whittling me down and as I'm following Vehumet very often I can't regenerate enough health to continue, and have to go back to the vestibule and rest. I have incredible single-target damage, controlled blink, haste and statue form, but absolutely no way to clear large groups of flying enemies. I just finished all my saved permafood [72 pieces, 32 bread and the rest meat and beef jerky] and had to go to a store and get more.
I went into Gehenna and got abyssed somehow, barely surviving the endlessly respawning enemies in the Abyss, and just now realising that god damn I have not learned Regeneration I am out of my god damn brain, so I escaped from the abyss, left Gehenna, got regeneration and called it for today.
Tomorrow I'll see if I want to push for 15 runes, or just win, because this is seriously tedious and boring and really not much fun, and will post my dump to serve as a warning to others.
