Artifacts

What it is

Artifacts are passive run modifiers picked up alongside weapons and ship upgrades. Each artifact has an active triggered effect (a buff, a hitbox, a summon, or a stat change) plus a flat passive ship-stat bonus that scales by tier. There are 34 artifacts in the pool.

Stats / tables

Rarity tiers

Each artifact has 5 runtime rarity tiers. Tier 0 (common) shares its triggered-effect values with tier 1 (uncommon); the difference between common and uncommon is only in the flat passive bonus. Tier scaling on the triggered effect ramps from tier 1 (uncommon) up through tier 4 (legendary). Meta-progression XP between runs raises the rarity tier; tier does not increase mid-run.

Tier idx	Name	Color
0	common	9d9d9d
1	uncommon	1eff00
2	rare	0070dd
3	epic	a335ee
4	legendary	ff8000

Flat passive bonus by tier

Every artifact carries a thematic passive stat ramp independent of its active effect. The bonus value is identical across all artifacts at a given tier; the difference is which stat it boosts.

Tier	Flat bonus
common	10
uncommon	20
rare	30
epic	40
legendary	50

The unit depends on the stat: weaponDamagePct, fireRatePct, magnetRange, and luck are flat additive points; maxSpeed and damageReduction are percent multipliers on the base stat.

Categories

Category	Meaning
unique	Custom triggered effect on a specific signal or timer
stat	Modifies ship stats or triggers stat-buff bursts on signals
weapon	Autonomous entity on a timer (drone, force field, missiles, supercharged shot)

Damage tags

A subset of artifacts carry a damage tag matching the weapon damage-type system. The tag drives the visual palette and lets the artifact’s damage interact with type-tagged passives. Three artifacts carry a tag: companion_droid (energy), crate_buster (bomb), killstreak_rain (bomb). The remaining 31 artifacts are tag-agnostic.

Trigger types

Trigger	Behavior
run_start	Fires once at run start; applies a permanent effect for the rest of the run
timer	Fires repeatedly on a fixed interval
timer + reset	Fires when N seconds elapse without the reset signal (used for “stay clean” buffs); the reset signal cancels the buff
signal	Fires every time the named signal is emitted
signal + cooldown	Fires on the signal but with a minimum re-trigger gap in seconds
counter	Fires when the named signal has been emitted N times; counter resets to 0 after firing
aura	Fires on a fixed scan interval (1s) for continuous re-evaluation

Full artifact catalog

One row per artifact. Magnitude column lists the legendary (tier 4) values; lower tiers scale down. Where the effect fires on every proc, “max stacks” is the maxStacks cap on the buff (1 = refresh, N = stacks up to N).

How it works

A pickup grants the player an artifact at the artifact’s current persisted rarity tier (carried over from previous runs via meta-progression XP). At run start, the artifact’s triggered effect is registered with the engine and its flat passive bonus is added to the matching ship stat. Triggered effects fire according to their trigger type and run for the rest of the run. The flat passive bonus stays on as long as the artifact is equipped.

Triggers fire on engine signals or on a timer. Signal triggers include player_damage, player_healed, enemy_kill, kill_streak_milestone, event_complete, crate_break, level_up, weapon_fire, and run_start. Timer triggers fire repeatedly on a fixed interval; some have a reset signal that delays the trigger when the signal fires. Counter triggers fire when their watched signal has been emitted N times since the last trigger.

Stat-buff actions on triggered effects use a stacking field that is usually ‘refresh’ with maxStacks 1 — re-procs reset the duration but do not stack. A few artifacts stack: reactive_plating stacks up to 15 stacks of DR and damage; armor_shred applies the shredded status on enemies up to 8 stacks per enemy.

Damage-AoE actions on procs are either centered on the ship or centered on the signal source. Centered on ship means the hitbox spawns at the ship’s current position; centered on signal means the hitbox spawns where the triggering event happened (for example, energy_kill_nova at the killed enemy’s position).

Interactions

• Sympathetic Resonance fires when any weapon is upgraded and adds bonus levels to every other equipped weapon. At legendary that is +3 levels per other weapon per upgrade pick.
• Phase Splitter (echo_generator) increases the projectile count of every weapon at run start. Stacks with the more_projectiles upgrade.
• Versatility (Omni-Tool) re-evaluates the equipped damage-type set once per second and applies +90 weaponDamagePct flat per distinct damage type at legendary (max 4 types = +360 weaponDamagePct).
• Personal Space writes the private _knockbackForce and _knockbackStun stats so every hit (from any weapon) applies knockback and stun.
• Lodestone and Breacher Charge both trigger on crate_break: every crate becomes an instant luck buff plus a damaging shockwave.
• Event Healer, Datacore, and Witness all trigger on event_complete: every event finish stacks heal + invuln + free upgrades + damage burst + AoE ring.
• Vitality Surge, Caretaker, and Echo all trigger on player_healed: every heal stacks damage + magnet + luck + fire rate buffs plus three concentric kill rings.
• Frenzy, Aegis, Salvager, Bloodlust, and Killstreak Rain all trigger on kill_streak_milestone (every ×10/×25/×50/×100/×200 streak): five stat buffs and ring/orbital damage burst together.
• Overdrive, Slipstream, and Hunter all use counter on weapon_fire with different thresholds: shot-spamming weapons trigger this triple frequently.
• Battery Shield and Trigger Happy also use counter on weapon_fire but with much higher thresholds (15 / 150 shots).
• Killchain Coil and Devourer both use counter on enemy_kill with different stat outputs (damage vs speed) and thresholds (15-30 vs 8-15 kills).
• Heartstone uses counter on player_damage with a 3-5 hit threshold and grants brief DR plus a damage AoE.
• Combat Stim and Kinetic Barrier both use the timer-plus-reset pattern with player_damage as the reset signal: avoid damage for the timer and a sustained buff activates until the next hit.
• Wayfinder, Stockpile, Adept, Phase Splitter, Combat Drone, Shield Emitter, and Gravity Pulse all fire at run_start and last the whole run.

What it does NOT do

• Artifact rarity tiers do not change mid-run. Tier-ups happen between runs from accumulated artifact XP.
• The Reactor Breach (meltdown) full-screen blast and the Stun Coil global stun pulse do not trigger any signal that other artifacts subscribe to (no chain-trigger).
• Damage-tag pills on the reward card are cosmetic identity only; only three artifacts carry a damage tag (companion_droid: energy, crate_buster: bomb, killstreak_rain: bomb). The remaining 31 artifacts have no damage tag.
• The bowling flag on Gravity Pulse (legendary tier only) is the only tier-gated boolean upgrade beyond standard scaling.
• Common tier does not have its own triggered-effect values; it shares uncommon’s values and only differs in the flat passive bonus magnitude.
• Triggered effects do not consume charges or resources. Cooldowns are per-effect and engine-driven; the player has no resource bar tied to artifact procs.
• Sympathetic Resonance has no run_start, signal, or counter trigger in its data file; the level cascade is implemented in the leveling system, not the effect engine.
