Info
- Arcsphere is Gyre’s ability 1.
- Launch a Gyratory Sphere that will deal high damage on impact and periodically deal electrical shocks to nearby enemies.
- Use it with the rest of the kit — especially Coil Horizon, Cathode Grace — instead of casting it in isolation.
- Ability Strength, Duration, Range, and Efficiency each matter differently; check Mod Scaling below before dumping all four.

Max rank drain ~9; see rank table on the augment page.
Cast Changes
- Modifies Arcsphere with: Arcsphere Augment: Projectiles that pass through Arcsphere have guaranteed Electricity Status Effect and +75% Electricity Damage.
- Rank up the augment to unlock the full effect values.
- Costs a mod slot (and capacity) — only equip it when the change matters for your loop.
Worth the Slot?
- Worth it when the augment’s change is central to how you play Gyre.
- Skip it if the base Arcsphere already does what you need and you’d rather keep the slot for survivability or strength.
Tips & Tricks
- Read the battlefield first — cast Arcsphere when it actually solves the room, not on cooldown habit.
- Pair Arcsphere with movement and energy economy so you’re not stranded after a big spend.
- On Steel Path, confirm whether Arcsphere still carries without strip, Viral, or a squad buff.
- If you never press 1, it’s the first Helminth candidate on Gyre.

Mod Scaling
Strength
- Improves Arcsphere’s damage or effect potency where Strength is listed on the ability.
Duration
- Duration is low priority on Arcsphere unless an augment or lingering effect needs it.
Range
- Increases Arcsphere’s reach, radius, or targeting distance.
Efficiency
- Arcsphere costs energy each cast — Efficiency (or strong regen) keeps the loop comfortable on long missions.
Priority
Stack the stats that actually move this ability’s needle, then Efficiency for uptime.
Mission Use Cases
| Mission | How to Use It |
|---|---|
| Steel Path Survival / Defense / Disruption | Test whether Arcsphere still clears or enables clear when enemies are dense and overlevelled. |
| Mobile Defense / Excavation | Use Arcsphere to control or delete the swarm on the objective, then reposition. |
| Exterminate / Capture Speed Runs | Cast Arcsphere only when it saves time — skip it on empty tiles. |
| Spy / Rescue / Quiet Routes | If Arcsphere is loud or forces combat, save it for after the vault; if it’s stealth-friendly, use it to stay safe. |
Comparisons

Vs similar tools on other frames — Arcsphere is tuned for Gyre’s loop — don’t judge it as a standalone subsume without the rest of the kit.
