the absurdly long completion time is due to me getting tripped up in the beginning hall. i was killing efreets with divine punishment, and it turns out if you take too long to kill them after one has died, they start respawning. so, 15 minutes of mana regen later, i killed them all with blade barrier. all in all the beginning hall took 30 mins ><
the queen fight was pretty easy, although i died about halfway through due to getting careless, then i died again at the last second but divine punishment finished the job
I used no mana potions, and i had never attempted this solo before.
