Phainon-Mortenax Blade vs AA Swarm (0c) First Clear | Anomaly Arbitration 4.3 | HONKAI: STAR RAIL

Don't have his FUA/Nihility teammates yet so I tried him in my invested Deliverer comp instead. I must say, he's definitely a great generalist debuffer~ Currently enjoying ~100% def shred – via Khaslana’s sig and E1 Harmonies – alongside high dmg vuln. Moreover, getting his E1 is truly nice for that juicy Res Down... Vonwacq (and Hit RNG) also helps a lot in getting ult fast ^^ #HSR #HonkaiStarRail #StarRail #Phainon #MortenaxBlade #Mortenax #Blade #Sunday #Cerydra #AnomalyArbitration #AA #Swarm #Honkaistarrail #HSRvideo #HSR43Guide #HardChallengeMatch43 Characters and Lightcones used: DPS: Phainon E2S1 Buffer: Mortenax Blade E1 w/ Tutorial LC Buffer: Sunday E1 w/ Bronya LC Buffer: Cerydra E1 w/ DDD LC P.S. Can do lower costs (e.g. E0S0 Blade) with better bounce RNG. Personally got Swarm King down to 6% with E0 Mortenax, but won’t sweat doing several resets lol *Build also shown at the end
