ModerniaInformation and Guide

Like Scarlet, Modernia is a proven PvE character, but she also got powercrept.

In short, Modernia's supremacy in the past was rooted in three major things: she was the only good MG user; her basic attacks hit 2 times each time, which compensates for her weapon's low natural burst gen; and her Burst provides infinite ammo + constant AoE clearing for 15s. Today, the first one no longer holds true, and the second one is useless since we've got better burst gen units now (like most Sniper Rifle/Rocket Launcher users). The last one is still a niche that exclusively belongs to her, but there is a shortcoming, and there are better alternatives already. The shortcoming is that Modernia's lack of self ATK buff (her S2 is not enough) + extended Full Burst actually sabotage the team in later Campaigns; she can't clear mobs fast and also gimps her team's output. Sure, she is still good at dealing with projectiles, Glass (who has a hitcount shield), and Mother Whale, but there are better alternatives you can use—such as Rapi: Red Hood, Alice, Asuka, SBS, Ein, and RH. That doesn't mean Modernia is completely out of the picture, however, because she is still good for Campaign, just not used as often anymore by veterans. If you're a beginner, and you have her, by all means use her.

For Bossing, you don't want to use Modernia's Burst Skill, which is another problem here. She is fully restricted to off-burst (must run 1-1-3 or you lose damage; may not applicable to beginners without OL because Modernia will be reloading over and over, in which case bursting with her might actually yield more damage + if you don't have CDR, definitely burst with her to extend FB time). In today's meta, 1-1-3 is not as popular as it used to be, and teams revolve more around "specific units with specific supports" (e.g. SG/Cindy teams), 2 DPS with a broken Support to enable Crown, and most duo Supports (Maids, Tia Naga, Blanc Noir). But, you're right: 1-1-3 comps are still used. The problem? There are better off-burst units than Modernia. For Supports, units like SHelm, Maxwell, Red Hood (for alternate B1), HelmTr, Naga, and sometimes even Noir can out-impact Modernia. For DPS, there is Mihara, who is pretty much an upgrade over Modernia (the 2025's Modernia, in other words).

Does that mean Modernia is out of the picture for Bossing too? No. Well, you see, Modernia still remains one of the better Fire DPS due to her off-burst damage. In Fire-weak Solo Raids, for example, we can easily expect her to be used. This may not be true all the time, but even if she ends up not being used by top rankers, you can use her with no issue, esp. with Asuka and Rei (collab chars), who are two of her best supports right now. In other SRs, she definitely has no place anymore—but, if you don't have a complete roster, she is one of the best alternative DPS.

In PvP, Modernia is a bad unit but still usable for one certain purpose, but this is only for beginners since there are safer ways of doing the same thing in late game. You can use Modernia as off-burst to pressure P1, or grasps on Modernia's actual strength in PvP: her Burst hitting 2-3 targets at once (target + adjacents). When you don't have better units, this is extremely useful as it can slowly whittle down poorly set-up Biscuit comps and P1-tank comps. Her extended Full Burst also helps maintain team's damage for an extra 5s, but this is not good for veterans who seek double rotations.
