Lock-on pistol. Cursor count scales with Amount, fires ignore Duration entirely.
Eagle Gun is a lock-on pistol that paints cursors on nearby enemies and fires at each one. The wiki specifies that Amount controls the max number of locking cursors, so every Amount source feeds directly into the weapon's target ceiling rather than just adding a second shot. That single rule reshapes the entire passive priority.
The second buried mechanic is the Ignores Duration tag. According to the wiki, Eagle Gun bypasses Duration scaling entirely, which means Empty Tome's Duration arc and any Duration arcana have zero effect on the lock-on cycle. Cooldown reduction is the only timing stat that matters here.
Build context. Eagle Gun is an Emerald Diorama DLC weapon, unlocked by leveling it to 6 in any run. It is the second optional starting weapon for Formina Franklyn on her Solo Eagle Gun skin, which itself unlocks by fully evolving the Saber Machine Gun. The Kugutsu "Boh" skin also starts with Eagle Gun.
This guide covers the Amount-equals-cursors mechanic, the Pendragon evolution that gates on Spinach plus the Falconfire glimmered tech, the Diva No. 5 unlock chain that fires on max-level Pendragon, the best Formina Franklyn build, and the Intuition selector route for non-Emerald Diorama characters.

Duplicator, Spinach, and 
Empty Tome. Amount, Might, and Cooldown only.Eagle Gun runs on a 4-second base Cooldown. Every activation paints a cursor on the nearest enemy and fires a bullet, then queues the next cursor. Per the wiki, Amount sets the maximum number of simultaneous cursors, so a stacked Duplicator turns the weapon from a single-target sniper into a four-target lock-on rifle.
Damage starts at 5 and scales with Might. The wiki effects block specifies that the weapon Ignores Duration, which means every Duration-related stat is silently dropped on the cycle. Pendragon inherits the same ignore, so even the evolved form gets nothing from Empty Tome's Duration component or the Wicked Season arcana.
Eagle Gun is not blocked by walls. In actual play, that lets cursors paint enemies around pillars and corridor edges on the Emerald Diorama stage. The Projectile Interval of 0.2 seconds is fast enough that a four-cursor lock-on fires its full salvo before the next Cooldown reset.
Take Duplicator on the first level-up screen you can. Each +1 Amount adds another lock-on cursor, which is the single best damage multiplier on this weapon. Two Duplicator picks is worth more than four Spinach picks for total DPS, because Spinach only scales the per-bullet number while Amount adds new bullets entirely.

Limit Break adds Base Damage, Amount, and Area in small increments, but the wiki lists Amount as the rarity-1 standout. Each Limit Break +1 Amount adds another lock-on cursor, which is the same compounding-by-multiplication payoff as the early Duplicator stack but with no inventory slot cost.
Eagle Gun evolves into Pendragon at max level with two gating requirements rather than the usual single passive. The wiki specifies the gates as max-level Spinach AND the Falconfire tech glimmered during the run. Falconfire is an Emerald Diorama tech, not a regular passive, so it shows up via the tech-glimmer mechanic rather than standard level-up offers.
Pendragon retains the lock-on behavior and can additionally glimmer the Bounding Shot tech. According to the wiki, fully evolving Eagle Gun into max-level Pendragon unlocks Diva No. 5 as a playable character, which feeds the Mr. S unlock chain further downstream.
| Base | Required | Becomes |
|---|---|---|
| Eagle Gun (max level) | Spinach (max) + Falconfire tech (glimmered) | Pendragon |
Bait the Falconfire glimmer early by holding the lock-on direction. The tech glimmers from the Eagle Gun itself under specific firing conditions per the wiki, so the longer the weapon runs at level 6+ with continuous lock-ons, the earlier Falconfire appears. Skipping Falconfire by accident is the most common way to brick the Pendragon evolution.
Formina Franklyn's Solo Eagle Gun skin pairs the lock-on starter with her core passive: gains Duration when using glimmered techs. Even with Eagle Gun ignoring Duration directly, the Duration ramp still scales every other weapon in the run, so the build leans into glimmered techs to feed both ends of the kit.

Saber Machine Gun (Formina's alternate weapon evolves separately; covers AoE while Eagle Gun snipes)In our testing, this build is online around minute 10 once Duplicator hits 2 and the Falconfire tech glimmers. Past minute 18, Pendragon takes over with the Bounding Shot tech adding bounce-on-impact, and the cursor-painting visual gets dense enough to read every priority target at a glance.
The wiki compatibility table flags Amount and Cooldown sources as green checks, while Duration sources are explicit incompatibilities because Eagle Gun ignores Duration. Duplicator and Empty Tome Cooldown remain the standout passives. Spinach still works because Might scales per-bullet damage independent of Duration.
For arcana picks, Game Killer (XX) is the standout. Per the wiki, Game Killer temporarily disables enemy projectiles, which lets the lock-on cycle paint cursors without taking chip damage. Mad Groove (VIII) is the alternative when the run already feels safe, since the gem-pull AOE feeds both Spinach scaling and Crown Growth at once.
Across multiple runs, Eagle Gun pairs cleanly with non-Emerald Diorama weapons that share the Amount-scaling pattern. The wiki notes that Intuition can select Eagle Gun on non-Emerald characters, so any character running Intuition as their selector slot can pick up Eagle Gun and the Pendragon path. Mr. S starts with Intuition by default.
Eagle Gun and Saber Machine Gun are both Formina Franklyn starters, and the wiki notes that fully evolving Saber Machine Gun is what unlocks the Solo Eagle Gun skin in the first place. Mechanically they are opposites: Saber Machine Gun sprays in a forward arc and benefits from Duration, while Eagle Gun locks-on individual targets and ignores Duration entirely.
Pick Eagle Gun when the run wants single-target priority damage on tougher enemies (Reapers, stage bosses). Pick Saber Machine Gun when the run wants forward-cone wave clear. In practice, the two cover opposite combat profiles, so most experienced Formina runs aim to have both online by minute 12 via the Intuition selector on the secondary slot.
Eagle Gun and the Pendragon evolution reference the Pendragon character lineage in the Emerald Diorama setting, which the wiki frames as a glimmer-tech narrative rather than a Castlevania-style heritage weapon. The Falconfire tech naming follows the Emerald Diorama convention of bird-themed glimmered techs, alongside Falconwind as a separately glimmered tech in the same DLC.
Diva No. 5 was added alongside Formina Franklyn in the 10 April 2025 Emerald Diorama update. Per the wiki, Diva No. 5's primary starting weapon is Super Missile and her Virginia skin uses Twin Dragon instead, but the unlock that gates her exists on the Eagle Gun evolution rather than her own weapon line. The unlock chain continues to Mr. S, who starts with Intuition by default.
