[Hades II] Unseeded 50 fear underworld (

Fraud alert: I bought Preserved Hope, and nobody stopped me. I then proceeded to take no damage (except into Trusty Shield) for the next four chambers, which I've heard is optimal when you have Engraved Pin and 20 HP. Mostly, I was terrified of losing the run by incorrectly calling last wave.
Honestly pretty dumb how much better runs with Prism will be than runs without, and yet the game is allowed to randomly screw you with terrible path of stars trees that don't have it. As far as I can tell, the ideal setup is Prism + Ferocity + Hera attack for maximum roomclear.
For some reason, I thought I had Ionic Gain during Cerberus and started to run around looking for it for a moment before remembering I had Tranquil Gain instead. Amazed I survived that fight with how terribly I played it.
