A Rapid Burst build trivializes the entire encounter (off-element). A single Provisional Forest buffed Burst without other buffs or debuffs can obliterate stage 2, allowing a smooth transition into stage 3 with all debuffs ready. A regular Burst with debuffs applied can destroy most of the Stage 4 mobs, leaving only a single mob up for more than 2T to recover CDs. Yet another buffed Burst on Jorm gets you at least half the way to Rage, with sufficient time to ready another Burst. Overdrive extension was helpful for delaying the punishing overdrives, which are the only real threat. If my ATK debuffs hadn't fallen off due to severe server lag I would've gotten the 'all survived' clear, but I had to settle for the 15T clear. Next time I'll let her overdrive before pushing into Stun I guess.
