Adding to what the other guy said Flourescent Lamp synergizes with Barbed Snare (both starting gifts btw) as the effect that gives every enemy Rupture happens _before_ the check to see how many status boosts Flourescent Lamp should give, so you get the maximum amount of buffs each time!
I noticed that at floor 2 you wanted to get Rodya's S3 but then screen cutoff and you came back into shop without it bought. I heard it's a bug with shop, where you can quit and all the previous decisions you've made get rolled back without using cost. How do you do it - just hard quit the game? I always wanted to try it to rig one of my runs.
I haven't heard about the bug you're talking about, so I'm not sure how you would do it. What happened here was a crash, if you check the recent announcements the game was crashing whenever you tried to replace a skill.
chef ryoshu support passive heals a flat 15 hp on enemy kill and g corp gregor support passive heals 5 hp after winning a clash. the extra 1hp is probably just due to rounding or something
