Arsenal
Primary
Hit Crystallize growths for forced red crits — status guns love Prismatic Gem priming.
Melee
Companion
Free-moving companions carry Prismatic Companion — sentinels do not.
Playstyle
Preserving Shell first — top DR with kills/assists, Fractured Blast for orbs, Gem for squad status. Crystallize is optional.
Passive abilities
Affinity-range health regen scales with Health Orb pickups. Fractured Blast feeds that loop — Strength toward ~200% locks health/energy orb chance and Preserving Shell’s DR cap.
Active abilities
- 1 Fractured Blast — Slash stagger + orb bait. Common Helminth slot when Nourish covers energy.
- 2 Preserving Shell — Decaying DR for you and allies — keep kills flowing to top it back up.
- 3 Prismatic Gem — Status beams + status chance/duration aura. Prismatic Companion sticks it to a free-moving companion.
- 4 Crystallize — Paralyze + guaranteed red-crit crystal weak spots. Recrystalize spreads on crystal kills.
- Keep Preserving Shell. Prismatic Companion recommended for mobile support.

Mission Usefulness
Steel Path Survival / Defense / Disruption
Preserving Shell + passive regen is the squad’s SP comfort blanket.
Mobile Defense / Excavation
Shell the objective, Fractured Blast for orbs, Gem for status.
Exterminate / Capture Speed Runs
Support loop is slower than a pure delete frame on empty tiles.
Spy / Rescue / Nightmare
Not a quiet kit.
Open World / Bounties
Squad-friendly camps and defense stages.
Long-Range Gunplay / Eidolon-Style Content
Shell helps survive hunts; Citrine is not an Amp specialist.
