RUN Empyrean Armor Quest

This probably becomes available after you beat it the first time, as I have not completed it yet and he has no option to teleport me :|

So I was banging my head against this for a while, read the darksday idea strat, finally got my ***together and went to do it. My 1hr was down from something else I was doing and I fully intended on losing a couple times to get the strat down, but the fight was absurdly easy this time around. No icarus wing, no 1hr use, did use a vile elixir NQ as a safety precaution, though. Pictures of my battle log for anyone who is interested.

I adjusted the Darksday strategy and found it worked even better this way. For reference the GSD I used is a fully upgraded Aettir. I started the fight on Lightningday.

When I did my first WS the NM was around 85~% and was dropped heavily by the Light SC damage while triple Lux Gambit had its light resistance lowered. My HP was at around 238 when I won. Could probably pop Vivacious Pulse for some extra insurance.
