Overview
Quell is a tier 4 Erekir-exclusive transport/combat unit that fires long-range homing missiles and projects a repair-suppression field. It upgrades from 

Quell’s armament fires two barrels at a moderate rate and launches a physical projectile that later produces a unit-missile frag. The projectile deals roughly 52–52.5 damage, cannot hit air, and spawns a missile unit on death; the spawned missile has about 45 health, deals a large area hit (listed as ~110 area damage over roughly 3.1 tiles), and is fast. The Quell’s range was adjusted across versions and is currently displayed at about 45.1 blocks. Its suppression ability disables enemy structure repair for 8 seconds and also affects unit repair towers.
Quell was added in Build 136 and has undergone several balance changes: hull health and armor reductions, range tweaks, a rule change that it no longer targets air, weapon behavior changed so the missile unit now spawns as a frag from the physical projectile, and payload capacity expanded to 4×4. The unit’s missile launchers feature an opening and closing animation.
Practical usage and interactions:
- Quell excels at long-range bombardment and can act as a mobile platform for suppressing enemy repair structures while its missiles absorb incoming projectiles because the spawned missiles count as units that can be hit. This can protect advancing ground forces and allow safer entry into defended bases.
- The initial projectile is not a unit; it can be deflected but will continue to aim for the original target position. The actual missile unit appears when the projectile despawns or strikes, improving hit-chance at closer ranges.
- Quell cannot attack air; massed air units such as Obviates or Averts counter it easily. Strong air defense (
Disperse turrets, Obviates/Averts) is recommended to protect Quells when used offensively.
- High-rate-of-fire turrets like Disperse can overwhelm Quell missiles, so attacking from multiple directions or using a Core Unit to pick up and expose enemy blocks to redirect turret fire can improve success.
- Outside direct combat, Quell is a valuable logistics unit: it can pick up T1–T3 ground units as well as Eludes and Tectas, move them over obstacles, and load units into payload systems for bulk upgrading or recovery via a Large Deconstructor.
- On campaign maps where Quells appear (
Karst waves and
Origin), they typically arrive in small groups and can be handled by forward Disperses or concentrated anti-ground defenses; however, if accompanied by ground forces their suppression and pickup capabilities make them more dangerous.
Build and behavior notes:
- Quell’s ship assembler recipe increased its Large Beryllium Wall requirement in an update.
- Unit Repair Towers are affected by its suppression field.
- The missile-frag mechanics and the separate missile unit’s HP mean the frag can absorb fire before dealing area damage, creating effective soft suppression and disruption of defenses.
