Witness
What it is
Witness is a stat-category artifact built around the event-completion signal. Every time the player finishes an event, the ship’s weapon damage briefly spikes and a wide resonance ring detonates around the ship, damaging every enemy in range. It is the largest-radius and highest-payoff member of the ship-centered ring family because its trigger — event completion — is the rarest of the three sibling signals, firing only a handful of times per run.

Per-tier values
The artifact ships four authored tiers indexed uncommon through legendary. A fifth common tier is prepended at runtime and shares the uncommon row’s named values; differentiation between common and uncommon comes from the artifact-wide flat passive bonus, not from this table.
Each proc carries four named magnitudes: the weapon-damage burst, the burst duration, the resonance-ring damage at the ring’s center, and the resonance-ring damage at the edge of the ring (with linear interpolation between the two).
| Rarity | Weapon-damage burst | Burst duration (s) | Ring damage at center | Ring damage at edge | Flat weapon-damage bonus |
|---|---|---|---|---|---|
| Common | +50 | 10 | 50 | 25 | +10 |
| Uncommon | +50 | 10 | 50 | 25 | +20 |
| Rare | +80 | 12 | 80 | 40 | +30 |
| Epic | +120 | 15 | 115 | 55 | +40 |
| Legendary | +180 | 18 | 160 | 80 | +50 |
The resonance ring has a fixed 280 px radius across every tier; only the damage values scale with tier. This is the largest radius in the ship-centered ring family of artifacts — explicitly larger than the kill-counter ring and the heal-echo ring — because the event-completion trigger fires only an estimated five to ten times per run, versus tens of procs per run for the kill-counter and heal-triggered siblings.
Effect
When the event-completion signal fires, the artifact runs the following actions in order. There are no gating conditions and the proc shows a banner.
| Step | Action | Parameters |
|---|---|---|
| 1 | Apply weapon-damage burst | flat additive on the ship’s weapon-damage stat, magnitude and duration from the per-tier table, refresh stacking, max stacks = 1 |
| 2 | Detonate resonance ring | flat damage with linear falloff from center value to edge value across the 280 px radius, centered on the ship |
| 3 | Play VFX burst-and-ring | bright color eebbff, 22 particles, scale 5.5, lifetime 0.50 s |
| 4 | Flash artifact HUD slot | accompanied by the artifact’s flavored audio cue |
The resonance ring uses linear falloff. An enemy at the ship’s center takes the center-damage value from the per-tier table; an enemy at the outer edge of the 280 px radius takes the edge-damage value; enemies in between take a damage value linearly interpolated between the two. The weapon-damage burst’s source tag is fixed to this artifact, so re-procs while the burst is still active reset the duration timer rather than adding a second buff instance.
Stacking rules
- The weapon-damage burst uses refresh stacking with a maximum of one stack from this artifact’s source tag. A second event completion inside the active window does not stack the magnitude; it resets the duration to the full tier value.
- Each proc fires its own resonance-ring instance. The AoE damage is applied per-proc and is not gated by any cooldown beyond the event-completion signal itself.
- Witness shares an event-completion-triggered design with two other artifacts (an event-heal artifact and an event-reward artifact). All three can be equipped simultaneously and each procs independently on every event completion — they do not share cooldowns or stacks. Equipping the triple means a single event completion fires a heal, a reward, and Witness’s weapon-damage burst plus resonance ring at the same moment.
- 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
Witness is an event-completion-triggered double payload: a refreshing flat weapon-damage burst and a 280 px ship-centered resonance ring with linear falloff. The burst magnitude scales 50 / 50 / 80 / 120 / 180 across common through legendary, the burst duration scales 10 / 10 / 12 / 15 / 18 seconds, the ring’s center damage scales 50 / 50 / 80 / 115 / 160, and the ring’s edge damage scales 25 / 25 / 40 / 55 / 80, with the flat passive weapon-damage bonus rising on the standard 10 / 20 / 30 / 40 / 50 ramp. The 280 px radius is fixed and is the largest in the ship-centered ring family, sized to compensate for the rarity of the event-completion signal.
EXTRACT-CANDIDATE flags
- The “four authored tiers plus one runtime-prepended common tier sharing uncommon’s values, with common-vs-uncommon differentiation from the artifact-wide flat passive bonus” rule is a general artifacts-system fact and belongs on the
artifactsroll-up page, not duplicated per entity. - The 10 / 20 / 30 / 40 / 50 flat-bonus per-tier ramp is shared by every artifact. Candidate concept page:
concepts/artifact-tier-mapping.md. - “Refresh stacking with max stacks = 1” is a recurring buff-stacking mode across most stat-burst artifacts. Candidate concept page:
concepts/buff-stacking-modes.md. - “Ship-centered AoE ring” geometry recurs across multiple artifact families (event-completion, kill-counter, heal-triggered). The family-level convention “larger radius compensates for rarer trigger frequency” is a balance pattern worth a shared page. Candidate concept page:
concepts/centered-aoe.md. - The event-completion signal and its multi-artifact triple-stacking opportunity (Witness + event-heal + event-reward, all proccing on the same signal) is a shared trigger concept. Candidate concept page:
concepts/event-complete-signal.md. - Linear falloff as a damage-AoE parameter (full damage at center interpolating to a separate edge-damage value at the radius) is an engine-wide effect-action capability and belongs on a combat or effect-engine reference page rather than a per-artifact page.
- The
flash_artifactaction plus banner-on-proc plus per-artifact flavored audio cue are shared behaviors across all triggered artifacts and belong on theartifactsroll-up or aconcepts/artifact-proc-feedback.mdpage.
