Firewhistle gud
DM-MO-1 5* Only 5 Ops
Cut down 1 op compared to my previous run from like 2 years ago, I had tried a strat like that before with Ashlock but she just didn't deal enough damage to the demolitionists and I didn't have Red raised. Now that Firewhistle is out, I managed to make it work. 4 Ops feels doable but that probably requires some Scene play and I'm garbage with Summoners so I'll pass.
There's not much to explain to the actual run, Bibeak is mostly needed because of the lancers, but her high physical DPS is super valuable to clear the basic sarkaz, and the arts damage + stun from S2 makes dealing with the demolitionists far easier. Red's super annoying in this case, as you need her to dodge once against basically every casters she kills. She can miss a few on the wave with 5 black casters, but on the last one missing any dodge would probably result in a reset. Even with Elysium slowing the flag guy a bit, Red could barely clear the right side before the casters would get buffed, and she can't handle buffed casters. Mulberry has the range needed to safely heal everyone that needs healing, Elysium does Elysium things, and Firewhistle provides arts damage from a safe range + blocks enemies.
