[Arknights] Can you beat SSS seaborn tower without stacks?

#Arknights #Ak #sss
I'm finally back from a 3 months hiatus due to IRL things
in this video I beat The Thirster; the main boss of The Abandoned Lighthouse in the Stationary Security Service game mode, in the Emergency difficulty without using Tactical equipment (Buff stacks)
About this clear: Eyja alter is the core medic and the first 4 maps aren't even worth mentionning. The difficulty however spikes in LT-5 because the Nethersea Brand softbans melee tiles (thanks to the enemies gaining ASPD per danger level and those Spewers with global range hit very hard) and the ranged tiles are a bit sparse
As for the boss in LT-6, his shield is a massive DPS check (especially the last one where it absorbes 90% of his HP AKA over 300k and lasts 20sec). my strat was to use his high DEF against him by having Ceobe be main DPS and debuffing his RES with ifrit while amplifying all arts damage with Reed saria and suzuran.
Here's the timp stamps:
LT-1: 0:08
LT-2: 1:03
LT-3: 2:37
LT-4: 4:18
LT-5: 5:24
LT-6: 8:39
