Emma: Tactical Upgrade + Eunhwa: Tactical Upgrade
PvPEmma: Tactical Upgrade· Eunhwa: Tactical Upgrade
A duo that trades fixed-damage (true damage) buffs with each other. Weak alone, but bound together they can put out burst damage in PvP alongside Vesti: Tactical Upgrade.
Two True DMG DPS Tag Together
CampaignEmma: Tactical Upgrade· Eunhwa: Tactical Upgrade· Vesti: Tactical Upgrade· Ein· Little Mermaid
[Source: prydwen.gg character page] This comp features TEmma as in-burst B1 and TEunhwa as in-burst B2. It also features Siren as off-burst B1. TVesti and Ein are incredible True DMG DPS for Campaign because True DMG ignores DEF, which is handy for High Deficit. Unlike our usual mobbing comps, this team doesn't feature Crown, so there is no shield to protect the team (it is replaced by continuous heal; but beware of one-shots!). This team can also be used for Bossing, but targeted B3 based on element is likely a better option. We only recommend using this team in Campaign against Fire-weak and Electric-weak. You can replace Ein with LaplaceTr for Iron-weak, but her compatibility with the team is lower (due to her playstyle and kit). LaplaceTr is also not as good as Ein for mobbing. You can also replace Ein with Rapi: Red Hood, who is a good bruteforcer and should work for most elements (plus good synergy with Siren). If your Ein is weak, then Rapi: Red Hood might even edge her out in Electric-weak, but for Fire and Iron-weak? Rapi: Red Hood is the way. Make sure you manual TEunhwa or Ein for fast burst gen; Siren will "complement" through TEmma's and her own high attack speed. Substitutions: Siren can be replaced with D:Wife, Volume, Dolla, SHelm, Rouge, or Sakura. Beware of Rouge's placement. If in the future ShiftUp releases a broken True DMG DPS that overshadows others even in Neutral, consider replacing one of the B3 with her.
Fire For Fire
BossEmma: Tactical Upgrade· Eunhwa: Tactical Upgrade· Vesti: Tactical Upgrade· Rei Ayanami· D: Killer Wife
[Source: prydwen.gg character page] A variant of the other comp but uses Rei as a team buffer instead. Since TEmma & TEunhwa are also Fire (same as Vesti), that means Rei can buff all of them. The effectiveness of this team depends on the investments (incl. dupes) of the trio. D:Wife is just an off-burst CDR. She can be swapped with any CDR, as long as they fit the team (preferably high-cap CDR who do not rely on Burst Skill for impact [SHelm is a fine choice, however]). DWife is used in this example because she is Fire (for exaggeration purposes only; she is not the best here). Substitutions: D:Wife can be replaced with Siren, Volume, Dolla, SHelm, Rouge, or Sakura. Beware of Rouge's placement. (Element: Fire)
Gladiolus
PvPCrown· Flora· Vesti: Tactical Upgrade· Emma: Tactical Upgrade· Eunhwa: Tactical Upgrade
[Source: prydwen.gg character page] Use Flora (Treasure) to instantly activate Crown's S2 and provide buff for TVesti.
Tactical Label
PvPMast· Emma: Tactical Upgrade· Eunhwa: Tactical Upgrade· Vesti: Tactical Upgrade· Label
[Source: prydwen.gg character page] Label can be used to deny Electric damage in the first 5 seconds. Using Label in Tactical, albeit not necessary, guarantees survival against fast Electric comps. This team utilizes Buff Overloading technique that makes Rosanna less likely to dispel Label's Damage Reduction.
Soline Makes Vesti Launch Torpedoes
BossEmma: Tactical Upgrade· Eunhwa: Tactical Upgrade· Vesti: Tactical Upgrade· Soline: Frost Ticket
[Source: prydwen.gg character page] This team is the basic Absolute formation with Soline as CDR to help with Water QTE breaking. EmmaTU already heals, though, so using Soline is less incentivizing here, but Soline gives great CDR! (Element: Fire)
