Devourer

What it is

Devourer is a stat-category artifact built around the kill-counter trigger. Every N kills, the ship’s engine surges with extra max-speed for a short window and a tight damage ring fires around the ship, hitting every enemy in close range. It sits at the mobility-focused end of the kill-counter family — lower kill thresholds, smaller AoE radius, and lower per-proc damage than its damage-focused counterpart, but more frequent procs.

Per-tier values

The four authored tiers cover uncommon through legendary. Per the artifact tier convention, the runtime prepends a fifth common tier that reuses the uncommon row’s named values and differentiates only via the per-tier flat passive bonus.

Rarity	Kill threshold	Max-speed bonus	Buff duration (s)	AoE damage (flat)
Common	15	+30%	5	15
Uncommon	15	+30%	5	15
Rare	12	+45%	5	25
Epic	10	+65%	6	35
Legendary	8	+90%	6	50

The kill-ring AoE has a fixed 180 px radius across all tiers; only the damage value scales with tier. The max-speed buff is applied as a percent modifier with refresh stacking and a single source slot.

Effect

Trigger: the enemy-kill counter signal. Every Nth kill (where N is the tier’s kill threshold) fires the artifact. The counter resets to zero after each proc.

On proc, the artifact runs the following actions:

Action	Effect
Max-speed buff	Adds the tier’s max-speed percent modifier to the ship for the tier’s buff duration. Source-tagged so re-procs refresh rather than stack.
Kill-ring AoE	Detonates a flat-damage ring centered on the ship with a 180 px radius. Every enemy in radius takes the tier’s flat damage value.
VFX	Plays a burst-and-ring particle effect in the artifact’s bright color (18 particles, scale 4.5, lifetime 0.40 s).
Artifact flash	Flashes the artifact’s HUD slot to signal the proc.
Audio cue	Plays the artifact’s flavored proc audio cue.
Banner	Shows the artifact’s banner on first proc in a run.

Stacking rules

• The max-speed buff uses refresh stacking with a maximum of 1 stack from this artifact’s source tag. A second proc inside the active buff window does not add a second speed buff; it resets the duration timer to the full tier value.
• Each proc fires its own kill-ring AoE instance. The AoE damage is applied per-proc and is not gated by any cooldown beyond the kill-counter threshold itself.
• The kill counter resets on every proc, so back-to-back procs require fresh kills equal to the full tier threshold each time.
• Tier upgrades replace the per-tier values record wholesale. Mid-run tier changes do not apply — tier is set at run start by meta-progression.
• Devourer shares the kill-counter trigger with at least one other artifact in the family; both can be equipped simultaneously and each procs independently on its own threshold without sharing cooldowns or stacks.

Summary

Devourer is a stat-category kill-counter artifact pairing a refresh max-speed buff with a flat-damage kill ring on every Nth kill. Threshold tightens 15 → 8 across common/uncommon → legendary, max-speed scales 30 → 90 percent, buff duration scales 5 → 6 s, and ring damage scales 15 → 50. The 180 px ring radius is fixed across tiers. The counter resets on every proc.

EXTRACT-CANDIDATE flags

• The kill-counter trigger model (counter signal: enemy-kill, configurable threshold, counter-resets-on-proc) is a shared concept used by the kill-counter artifact family (at least Devourer and Killchain Coil). Candidate concept page: concepts/kill-counter-trigger.md.
• The “5th common tier reuses uncommon’s named values and differentiates only via flat passive bonus” rule is shared across all artifacts and belongs on the artifacts roll-up page, not duplicated per entity.
• The flat-bonus per-tier ramp (10/20/30/40/50) referenced in _types.ts is engine-wide and should live on the artifacts overview / authoring guide.
• The modify_stat refresh-stacking semantics with single-source-slot enforcement is a generic effect-engine concept; canonical definition belongs on a combat or effect-engine page.
• “Centered AoE on ship” geometry (fixed radius, flat damage per tier) recurs across the kill-trigger ring-bearing artifact family. Candidate concept page: concepts/centered-aoe.md.
• Color-palette schema (primary / secondary / bright) is shared across all artifacts and belongs on the roll-up, with per-entity pages only listing the values.
• The shared action primitives (modify_stat, damage_aoe, vfx, flash_artifact) and the procAudioCue field belong on the artifact authoring guide as the canonical reference.
