The best setup for the Severian team comp in ZZZ is: Severian + Stun + Support/Buffer. For that, his best team is Severian + Norma/Roxy + Sunna/Astra Yao. Of course, he works with other Stun Agents too, but for the Support slot, he has more limited options.

It's easy to find a team for Sunna in Zenless Zone Zero because of her universal buffs that work with almost every character.

Severian needs either a Support Agent, Stun Agent, or an Agent from the same faction to trigger his Additional Ability. You can always do double support with Severian, but a Stun Agent is crucial if you want to continuously trigger Stuns and maximize DMG during the Stun window.

Roxy synergizes best with Severian's Additional Ability and Core Ability. She can also provide buffs for him. However, if you're looking for the best Stun Agent, then go for Norma. Alternatively, you can choose Dialyn to cast more Ultimates. Severian gains access to his Enhanced Basic Attack via his Ultimate, so Dialyn works great for that.

For the Support slot, Sunna can provide the most for Severian , followed by Astra Yao . If you don't have both of them, you can opt for F2P choices like Rina and Nicole . In terms of buffs, Sunna wins, but Astra Yao can create a unique synergy where she helps trigger Severian's Entry Skill with her Quick Assist effect. Meanwhile, Rina has to be M1 to be viable, and she can be amazing if you have her W-Engine on a high Refinement level.
