Skorpian is the projectile-stacking extreme chassis that fires multiple projectiles per trigger pull, scaling infinitely with part slot count. As the community-confirmed S-tier chassis, Skorpian can solo Act 3 with 8+ Projectile Fragment parts and the right keyword chain. The chassis's strength lies in its multiplicative scaling — every additional Projectile Fragment adds another projectile to every shot, which compounds with [Shatter] and [Growth] keyword triggers for runaway damage curves. Skorpian is the recommended first-clear chassis for experienced players who can manage part RNG; less ideal for new players who should start with the more forgiving Leaf Cutter chassis.

Leaf Cutter is the single-shot burst extreme chassis that channels all damage into one bullet per magazine, ideal for boss-melt builds that pair with [Final Shot] keyword. As the second S-tier chassis alongside Skorpian, Leaf Cutter excels in Act 3 boss encounters where a single killing bullet ends the fight. The chassis's strength lies in its amplifier-friendly design — Final Barrel and similar parts multiply the killing bullet's damage, which then triggers [Final Shot]'s massive amplifier. Leaf Cutter is the recommended first-clear chassis for new players because its low trigger rate is more forgiving of positioning mistakes than Skorpian's high-volume firing pattern.

Projectile Fragment is the cornerstone Weapon Part for any Skorpian projectile-stacking build, adding +1 projectile per trigger pull. As one of the most impactful A-tier parts, every additional Projectile Fragment compounds the chassis's damage output. The part is commonly dropped in Act 1, so players can stack 2-3 fragments before the Act 2 mid-boss, and 5-8 by the time Act 3 opens. The stacking cap is roughly 8 fragments before diminishing returns kick in, so the wiki recommends 6-8 fragments as the sweet spot for most builds. Projectile Fragment pairs especially well with [Growth] keyword, where every additional projectile counts toward the kill-scaling trigger.

Final Barrel is the +50% magazine damage Weapon Part that multiplies the killing-bullet damage on any single-shot chassis. As one of the strongest A-tier parts, Final Barrel pairs with Leaf Cutter and [Final Shot] keyword for boss-melt builds where the killing bullet's damage matters more than trigger rate. The part's strength lies in its amplifier design — the +50% applies to the final bullet in the magazine, which then triggers [Final Shot]'s massive amplifier for compounded damage. Best paired with the One-Eyed Codger's Snipe Ultimate for the maximum single-shot damage spike.

Fire Coil is the elemental fire-damage-on-hit Weapon Part that adds fire element to any chassis. As a strong B-tier elemental part, Fire Coil pairs with Fire Coil Relic for compounded elemental damage that stacks on top of [Shatter] triggers for max burst. The part's strength is its elemental layer — fire damage applies on every hit, which compounds with chassis-level fire effects and the Fire Coil Relic for triple-stacked elemental burst windows. Best paired with Skorpian Fireworks Master for screen-wide fire volleys that clear rooms in seconds. Elemental reaction windows also trigger with ice/lightning/poison for compound elemental combos.

Lightning Coil is the elemental lightning-damage-on-hit Weapon Part that adds chain lightning to any chassis. As a strong B-tier elemental part, Lightning Coil pairs with Lightning Coil Relic for chain-lightning bursts that hit multiple enemies per trigger. The part's strength is its area-of-effect damage — chain lightning jumps to nearby enemies, which compounds with Skorpian's projectile-stacking for screen-wide chain damage. Best paired with high-trigger-rate chassis for maximum chain-lightning triggers. Elemental reaction windows with fire (lightning + fire = plasma) create compounded elemental damage spikes that exceed any single element's output.
