Serena

Serena

Tier SSeason 2 EP2 / Season 3 era

Overview

Serena's power is uptime. If you keep flying and keep firing, she scales brutally. The build is about cooldown control, survivability, and weapon synergy—not ground AoE farming.

Best For

Bossing and hard encounters where sustained firearm DPS and safe airborne positioning create long uptime windows, plus teams that benefit from her Blessing/support interactions.

Best For

  • Colossus / boss fights (sustained firearm DPS)
  • Hard-mode progression where safe positioning matters
  • Elite/priority target deletion
  • Co-op teams (support interactions / Blessing uptime)
  • Players who like airborne gunplay

Strengths & Weaknesses

Strengths

  • Exceptional sustained firearm uptime while airborne
  • Strong survivability through positioning (fighting from above)
  • Scales extremely well with weapon investment
  • High value in coordinated boss encounters
  • Has ally-support utility via Blessing/heal-adjacent interactions

Weaknesses

  • Lower value in pure speed-farm AoE loops compared to Bunny/Valby
  • Requires cooldown discipline to maintain airtime loops
  • If grounded/forced to disengage, performance drops sharply
  • Weapon quality/synergy matters more than on skill-casters
  • Execution-heavy: positioning + aim + uptime management

Alternatives

Swap in if you're getting clipped by ranged fire during airborne loops in Hard content.

Maximize Conservation

If resource pressure is limiting airtime skill cadence.

Build Variants by Progression

Low-investment airborne learning build: prioritize survival + basic weapon output while you master airtime control.

Stat Priority & Reactor Guidance

Stat Priority

Primary

  • • Firearm ATK
  • • Weak Point Damage
  • • Weapon Critical Hit Rate

Secondary

  • • Weapon Critical Hit Damage
  • • Skill Cooldown Reduction
  • • Max HP

Avoid

  • ✗ Over-investing in AoE skill stats for farming
  • ✗ Glass-cannon weapon stacking without HP/DEF
  • ✗ Pure skill-power builds that sacrifice firearm uptime

Reactor Guidance

Preferred Type:

Fire

Preferred Skill:

Singular

Best Stats:

• Firearm ATK Boost

• Weak Point Damage

• Skill Cooldown

Reactor optimization should support weapon uptime (cooldown/survival) first, then amplify precision damage. Serena's value is sustained firearm DPS from the air.

Rotation & Playstyle

Rotation

  1. 1.Enter airborne state / wings loop before committing to a phase
  2. 2.Acquire weak point line-of-sight and sustain fire
  3. 3.Refresh airtime tools proactively (before you're forced to land)
  4. 4.Use support/Blessing interactions when allies are grouped or during safe windows

Tips

  • 💡 Treat airtime as a resource: refresh early, not late.
  • 💡 Pick angles where you can see weak points without exposing yourself to too much return fire.
  • 💡 If you're dying, add HP/DEF before adding damage—dead DPS is zero DPS.
  • 💡 Serena is not a map-clear farmer; she is a boss-phase shredder.

Farming Plan

Goals

  • Weapon DPS modules (ATK / weak point / crit)
  • Cooldown + resource sustain modules to support airtime loops
  • Reactors with firearm + weak point + cooldown rolls
  • External components emphasizing HP/DEF for Hard content

Recommended Activities

  • Boss/Colossus runs where sustained DPS matters
  • Hard-mode missions that punish ground exposure
  • Module farms for precision/weapon scaling pieces

Priority Targets

  • Weapons Platform (core)
  • Weak point + firearm scaling modules
  • Cooldown rolls that stabilize airtime

Scaling Notes

Serena scales multiplicatively with uptime: better airtime control + better weapon scaling equals enormous real DPS gains over an encounter.

Team Synergy

Pairs well with tanks/controllers that stabilize boss positioning and supports that keep you shooting through pressure windows.

Known Issues

If encounters force frequent grounding or line-of-sight breaks, Serena's real DPS drops significantly.
