Which xl8 Necro spell to use? CiP: xl23 GnTm on Tomb:3 stair

[Yermak]

I'm about to enter Tomb:3. If I drink one of my 4 pots of brilliance I can cast any of Necronomicon spells. So here is the question: which one would be better to learn?
Pros and cons:

• Borgnjor's Revivification fully heals, but chips off 7% of my maxhp. Permanently.
• Death's Door sets my health to 10, but makes invulnerable for ~20 turns.
• Infestation summons scarabs out of creatures I kill.
• Necromutation makes my gnoll immune to all mummies' shenanigans except smiting, but keep in mind that ushabti can cast Dispel Undead and bennu have holy-branded attack.

option F: amnesia conjure flame and learn both borg and ddoor, because ddoor is insanely good, and if you screw up using ddoor, you can use borg to not die

Yeah, Conjure Flame is what I'm going to amnesia to learn the spell in question. Can't learn both.

[duvessa]

oh whoops, right, you've only got 2 amnesia scrolls, and presumably don't feel like temporarily amnesiaing dmsl and irradiate

ddoor it is then!

[tasonir]

I'd vote revivification, sure the loss of hp sucks, but what sucks more is dying permanently. That said if you want to do DDoor that's fine too. I've always been a bit afraid of using death's door though, so I don't have much experience with it.

[nago]

You have 5 ?fog and !HW so if DD expires in a bad place you may survive the 3 turns to recast it once or twice quite probably.

But I'm curious on how you plan to take the rune: you have only 3 ?teleport and 1 ?blink, so rune stealing seems to me quite impossible.

If you're planning to got it killing anything between, infestation may be better.

[pedritolo]

DDoor, for sure. Does it work with statue form? abjur+ddoor+immol seems like a great combo if things go sour

Edit: since you're on a speedrun, infestation will be a LOT more useful later on, while in hell/pan, to save turns. And it's not bad in tomb either.

[Yermak]

Guys, how exactly would you use DDoor in this situation? Since you can be killed at the turn DDoor expires, you don't want to have any relatively dangerous monsters next to you at this moment, otherwise your survival is decided by a coin-flip. To ensure that you either have to cBlink-fog (random blink wouldn't suffice since you cannot determine the moment exactly) or go to Tomb:2 and kill all followers there. First option this char could do exactly once (one ?blink), second seems to be unreal - you can't cheiwalk to the hatch while DDoor is on - it's duration will be out often before you reach it, and getting on the hatch before DDoor also seems problematic.
So, DDoor looked poor in my test runs. Borg was a bit better. The real champion turned out to be Infestation. It worked perfectly in the actual run allowing Me to get the golden rune. After that game was relatively smooth, I ended up winning in 17k+ turns.
