Nanite Swarm
What it is
A stat-category artifact that procs whenever the player is healed. Each heal pulse grants a brief stacked buff to weapon damage and magnet range, and emits a mid-radius damaging ring around the ship. Reward-card line: “When you heal, your damage and magnet range are boosted and a nanite-swarm ring damages nearby enemies.”

Per-tier values
The artifact ships four authored tiers (uncommon through legendary). The runtime prepends a fifth “common” tier above these by reusing the uncommon values record and differentiating via the shared flat bonus curve.
Per proc, the triggered effect carries four named magnitudes: damage-bonus value, magnet-bonus value, buff duration, and ring damage. The flat passive magnet-range bonus follows the standard artifact-wide ramp.
| Tier | Damage bonus | Magnet bonus | Buff duration (s) | Ring damage (flat) | Flat magnet-range bonus |
|---|---|---|---|---|---|
| Common | +50 | +110 | 10 | 22 | +10 |
| Uncommon | +50 | +110 | 10 | 22 | +20 |
| Rare | +80 | +170 | 13 | 35 | +30 |
| Epic | +120 | +250 | 18 | 55 | +40 |
| Legendary | +180 | +380 | 25 | 80 | +50 |
The nanite-swarm ring is a flat-damage AoE with a fixed radius across all tiers; only the damage scales with tier.
Effect
When the player_healed signal fires, the artifact runs the following actions in order. There are no gating conditions and the proc shows a banner.
- Weapon-damage buff — Adds the tier’s damage bonus as a flat additive to the ship’s weapon-damage-percent stat for the tier’s duration. Stacks
refreshwithmaxStacks: 1. - Magnet-range buff — Adds the tier’s magnet bonus as a flat additive to the ship’s magnet-range stat for the tier’s duration. Stacks
refreshwithmaxStacks: 1. Tagged with a separate source from the damage buff so the two timers refresh independently of any external magnet buffs. - Nanite-swarm ring — A damage-AoE pulse centered on the ship. Flat damage equal to the tier’s ring-damage value, applied to all enemies within the ring radius.
- VFX — A pink burst-and-ring effect.
- Artifact flash — Standard proc flash on the artifact HUD slot, accompanied by the flavored audio cue.

Stacking rules
- Both buffs are single-stack with refresh semantics: consecutive heals reset the remaining duration of each buff rather than accumulating magnitude. A second heal inside the active window does not stack the bonus; it resets the timer to the full tier value.
- The two buffs use separate source tags, so the damage and magnet timers are managed independently and neither blocks the other.
- Ring damage is per-proc and not gated by buff state — every heal pulse emits its own independent ring regardless of whether the buffs are already active.
- Family context: Nanite Swarm shares the
player_healedtrigger with two siblings. Its ring is the middle radius of the family; its ring damage sits between the other two because the stat-stack payoff is the primary reward and the AoE is a secondary bonus.
| Family member | Ring radius (px) |
|---|---|
| Echo | 160 |
| Nanite Swarm | 180 |
| Caretaker | 200 |
- 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 and does not increase during a run.
Summary
Nanite Swarm is a heal-triggered triple payload: a refreshing flat weapon-damage buff, a refreshing flat magnet-range buff, and a 180 px ship-centered AoE ring. Magnitudes scale 50 / 50 / 80 / 120 / 180 for damage, 110 / 110 / 170 / 250 / 380 for magnet, 10 / 10 / 13 / 18 / 25 seconds for buff duration, and 22 / 22 / 35 / 55 / 80 for the ring damage across common → legendary. The ring radius is fixed at 180 px (mid of the ship-centered heal-ring family) because the artifact’s primary identity is the dual stat stack, not the AoE.
EXTRACT-CANDIDATE: The player_healed artifact-family comparison table (radii, damage tradeoff philosophy across Echo / Nanite Swarm / Caretaker) appears here and on the sibling entity pages — candidate for promotion to the artifacts roll-up or to a concepts/player-healed-signal.md cross-reference page.
EXTRACT-CANDIDATE: The “runtime prepends a fifth common tier by reusing the uncommon values record, with common-vs-uncommon differentiation from the artifact-wide flat bonus” mechanic is artifact-system-wide and belongs on the artifacts roll-up, not per-entity pages.
EXTRACT-CANDIDATE: The 10 / 20 / 30 / 40 / 50 flat-bonus ramp is shared by every artifact — candidate concept page: concepts/artifact-tier-mapping.md.
EXTRACT-CANDIDATE: Refresh stacking with maxStacks: 1 and per-source-tag timer independence are recurring buff-stacking semantics across most stat-burst artifacts. Candidate concept page: concepts/buff-stacking-modes.md.
EXTRACT-CANDIDATE: Ship-centered ring geometry (fixed-radius flat-damage AoE centered on the ship’s position) recurs across multiple artifact families. Candidate concept page: concepts/centered-aoe.md.
EXTRACT-CANDIDATE: The flash_artifact action plus banner-on-proc plus per-artifact flavored audio cue are shared behaviors across all triggered artifacts and belong on the artifacts roll-up or a concepts/artifact-proc-feedback.md page.
