I've done it, the dumbest delve setup ever

Necromancer, Carrion Golem build, phasing flask, quicksilver flask, both have enchant to reuse at end of duration.

1.Start delve

2. When you see enemies, use both flasks

3. RUN!!

3.5. Minions kill just enough mobs to refill flasks, so u make it all the way there on 2 cheapo flasks and a janky minion build.

and by far the dumbest forum post..

Yes, and it is GLORIOUS! I call this build, "Ach! Hanz! RUN!"
