Katagawa’s Revenge is a Legendary Maliwan sniper with two firing modes that each flood the field with elemental damage. In Shock, it spawns hovering “storm” nodes that lock onto enemies and fire rapid lightning; in Incendiary, it creates clouds that drop and explode. It’s a standout pick for elemental and area damage builds, and it’s farmable from a single story boss once you unlock the arena.

Unlock Katagawa’s Revenge (mission path and location)

You’ll get to the weapon’s source as part of the main story. The boss you need is Driller Hole, tucked inside Queen’s Cradle in Tonnage Peel on Carcadia Burn.

Step What to do
1. Story prerequisite Finish the mission “Siege and Destroy.”
2. Mission unlock Start “Unpaid Tab.” This mission opens access to Queen’s Cradle and routes you to the boss arena.
3. Region path Travel to Carcadia Burn → Tonnage Peel → Queen’s Cradle and progress the objective into the Driller Hole arena.
4. Target Defeat Driller Hole. Katagawa’s Revenge is on his Legendary loot table.

Once you’ve cleared the fight the first time, you can use Moxxie’s Encore Machine to refight Driller Hole and farm his drop. As with all Legendaries, expect multiple kills before you see the sniper.

Driller Hole boss fight (damage types, weak point, pacing)

Driller Hole runs a two-phase script and carries two health bars: armor first, then flesh. He is slow but fires heavy rockets and leaves ground hazards behind.

Target Use this damage type Notes
Armor bar Corrosive Melts the first phase efficiently.
Flesh bar Incendiary Speed up the second phase burn.
Weak point Head (small hitbox) Crits chunk both bars; crouch-peek from cover.

Positioning matters more than sprinting. He lumber-walks toward you while saturating the room with splash and ground effects, so keep solid cover between you and the boss, and rotate around the center machine to kite him without losing sightlines.

Phase 1 attack patterns and counters

Attack What it looks like How to avoid
Vertical back rockets Missiles lift off from his back, arc upward, then drop onto your position. Strafe or backpedal out of the impact clusters; don’t stand in the lingering elemental puddles.
Direct-fire rockets Left-hand weapon launches homing shots on a straight line to you. Break line of sight with hard cover; move fast between pieces to shed tracking.
Burrowing explosives Drill-like rockets dive underground and travel along visible trails. Watch the ground; jump or dash off the path before they surface and burst.
Tip: You can continuously walk backward in a loose circle around the central machine, using it as rotating cover. His walking speed won’t catch you if you keep moving.

Phase 2 attack patterns and counters

Phase 2 doesn’t add new mechanics so much as volume. Expect denser volleys and larger splash zones.

Attack What it looks like How to avoid
Multi-volley back rockets Several arcs at once, landing in a wide fan in front of him. Create distance quickly; get fully behind cover to block overlapping splash.
Wave fire from gun Homing salvos in rapid waves from his left-hand weapon. Hard cover is safest; lateral dashes work if space is open.
Burrow waves (six total) Three underground explosives, followed by another three shortly after. Move perpendicular to the trails; jump or dash between waves to reset spacing.

With more splash and hazard pools in the arena, be deliberate about your kiting path so you don’t trap yourself. Keep aiming for the head and swap to fire damage to accelerate the final bar.

Farm Katagawa’s Revenge efficiently

After your first clear, head to Moxxie’s Encore Machine to re-run Driller Hole on demand. Keep your spawn point close to the arena to minimize turnaround, and tune your loadout for Corrosive → Incendiary swapping to shorten each kill. The weapon can also show up from the broader sniper loot pool, but boss farming is the most direct route.

Set realistic expectations: Legendary drops are random. Batch several runs per session and track how changes to your route or damage types affect your time-to-kill.

What makes Katagawa’s Revenge worth the farm

This rifle leans into Maliwan’s element-first identity. You can toggle Shock or Incendiary and get different crowd-control behavior from the on-hit clouds:

  • Shock: hovering nodes act like auto-targeting tasers, ticking lightning rapidly on enemies in range.
  • Incendiary: clouds form near targets and drop to the ground, bursting with fire on impact.

Because each projectile spawns additional damaging objects, you often delete packs by shooting once into the area and letting the secondary effects do the work. Builds that stack status effects or scale with frequent hits benefit most, but even general gun builds can lean on the sustained AoE to clear groups while you reposition.

If your kit already amplifies elemental procs or rewards high hit frequency, put this on your short list. Once “Unpaid Tab” is active, it’s a quick path to the boss and a repeatable farm for one of the game’s most reliable elemental snipers.
