Promeia Best Team Compositions and Character Synergies

Stunning an enemy and triggering Chain Attacks can allow Promeia to gain more resources towards her Ablooms. Pairing that with Nangong Yu's Anomaly buffs and personal DMG (that Promeia can buff) allows for decent synergy between the two. Ablooms from other Agents, such as Nangong Yu's, will also benefit from Promeia.

For most teams, Support Agents, especially Yuzuha, will be greatly appreciated for the buffs they provide. With Promeia, you can play a support agent alongside a second Anomaly Agent or alongside Nangong Yu.

Promeia would typically be played alongside other Anomaly Agents (or Nangong Yu) where the second Anomaly Agent applies their Anomaly to trigger Disorders and gain resources towards Promeia's Ablooms. Agents who can trigger Ablooms of their own, such as Vivian, Burnice, or Grace, can have even better synergy with Promeia as she gains even more resources when a squad member triggers Abloom.

Having a stun agent in your squad is not necessary, and will likely not be much better than having a Support Agent. However, some stun agents such as Von Lycaon or Lighter can be played together with Promeia without explicit synergy.

Von Lycaon can be played in Mono-Ice teams with Miyabi or teams revolving around Promeia's own Abloom DMG. In such teams, Von Lycaon allows for faster stuns, reduces Ice RES, and can even equip the Freedom Blues set for decreased Ice Build-Up RES.

Lighter can be played in teams with Burnice White, where alongside Burnice's Ablooms and off-field Anomaly Application, Lighter helps stun enemies faster and build some Fire Anomaly from on-field, while providing large damage buffs for both Promeia and Burnice.

With Promeia being an Ice Anomaly Agent, there is a chance that she can pair well with Miyabi. However, that is not likely to be the case, as both units don't have the best synergy. This does not mean they cannot be played together, and teams with both agents will likely be very strong - due to how much DMG both Agents can deal regardless. (In a very similar case to Vivian)

For Miyabi, Promeia does not provide useful buffs such as those that Soukaku provides in a Mono-Ice team, nor does she trigger Disorders like Tsukishiro Yanagi does. In most cases, Nangong Yu will likely be a better partner for Miyabi than Promeia.

For Promeia, Abloom DMG, the main source of Promeia's DMG, will be lower in teams with Miyabi. Miyabi is typically built for Crit and not Anomaly Proficiency, so Disorder DMG will be lower as a result, in turn reducing Promeia's Abloom DMG. This does not stop such teams from being strong, as teams with Vivian, who mostly shares the same issues with Miyabi, are still very popular due to ease of play and overall strong damage.
