Slayers 2 Weapons & Crafting Guide — Sides, Drops & Upgrades

Weapons in Slayers 2 are bought, dropped or crafted — never rolled. The official FAQ promises 10 at release (7 Demon, 3 Slayer), while documentation and the launch balance patch name 12. This guide lays out what’s confirmed about each, where it comes from, and how the upgrade systems work.

Sides: what’s actually confirmed

The weapon showcase Q&A settled exactly two attributions:

• Tanto → Slayer (dev-confirmed). A fast secondary blade: Phantom Barrage, Spiral Fang and Tanto Descent.
• Claws → Demon (dev-confirmed). A posture-focused brawler: Tri-Claw Reversal, Predator Claws, Feral Frenzy. The launch patch raised its Z damage by 35%.

Everything else follows community lists (marked “unconfirmed” in our weapons database until verified): Shotgun and Sickles read Slayer-adjacent and Blood-Sickles-themed respectively in creator documentation, while Bladed Wagasa and War Fans are boss drops on the Demon side of the map.

Where weapons come from

Vendors — the starter katana sells for 500 Wen, the fancy katana at 1,500 (documented vendor prices from early-game runs).

Boss drops (the interesting ones):

Crafting — the blacksmith in Mistfall Harbor opens a forge quest that also unlocks the endgame dungeon. The headline recipe at launch: the shotgun schematic, dropped by the Underground NPC in the Final Selection instance (about 5% per creator runs), crafted with ~100 metal scraps + silk thread + 25,000 Wen.

Style-bound weapons

Some weapons exist to gate or empower a breathing style rather than to be a main: the mason axe (dropped by the Stone trainee, required to train Stone Breathing), Sound’s dual cleavers and Stone’s axe-and-flail (community documentation). These likely sit outside the official “10 weapons” count — which is one explanation for the 10-vs-12 gap.

Upgrades: series items and refinements

Two systems stack:

1. Series items — equipment sets. The launch series are Nightfall and First Light; materials are multi-source (no single-drop lock) and the V.06 hotfix added a Series material exchange shop at the Blacksmith so spare materials convert instead of rotting.
2. Refinement upgrading — the late-game power curve. Creator runs document enhancement odds around 92% to downgrade, 8% to +1 and 0.5% to +3 at the top tier — bring spares, not your best piece.

Raid-tier bosses also drop Series Equipment sets (Armor, Haori, Mask with set bonuses) per community documentation.

Armor Penetration: the V0.25 gear stat

V0.25 (October 10, official changelog) added Armor Penetration, a Series-item stat that makes your hits ignore that share of the target player’s Damage Reduction Factor. It works against players only — it does nothing to NPCs or bosses. The published values:

The same patch cut the Firstlight side: Firstlight Top and Bottom dropped from 5% → 3.5% Damage Reduction Factor and 3% → 2% Max Health Factor each. In practice Nightfall is now the set that punches through another player’s mitigation, while Firstlight keeps less of its own damage reduction and health — the split the V0.18 set bonuses (First Light defensive, Nightfall Hunt execute) already pointed at.

How to get the Nightfall weapons

Nightfall is the piece players ask about most, and the route is part conversion, part treasure hunt. What the official Discord’s Q&A channels document (October 2026, multi-source unless noted):

• The katana starts from any Hashira katana. You do not need a specific breathing’s katana — “any” is the direct answer players get — and converting keeps your refinement level, so upgrade your tidal katana to +5 before turning it Nightfall, not after.
• The Serpent Katana schematic comes from a key hunt. Hidden chest keys are scattered around Mistfall Harbor — in the ocean nearby, to the left of the docks, and at least one fully underwater (players report hour-long dives for the last one). Collect them and the chest yields the Nightfall Serpent Katana schematic. The total key count is not published; reports of “collected every key, nothing happened” most likely mean one is still missing, though a bug has not been ruled out.
• Nightfall Sickles come from a lever puzzle. Pulling the world’s levers is the documented path to the sickles — the only Nightfall weapon bound to a specific build, since Sickles pair with the Blood Manipulation demon art and nothing else.
• Top and Bottom come last. The official prerequisite for the Nightfall top/bottom schematics is owning every other Nightfall schematic first. The Cape additionally consumes the Lost Cape, a fishing drop.
• Materials for a conversion (Nightfall gauntlet example): the damascus gauntlet plus a Nightfall schematic, roughly 1,000 metal scrap, 1,000 silk thread and 500,000 Wen at tier 0. Metal scrap is sold by the NPC Ginjo at Mistfall Harbor. Farming rates around 2% per boss kill make boss rotations and dungeon chests the standard supply — the crafting prices themselves are on the materials guide.

On which one is best: the flat Nightfall Katana carries +5 additional damage and is the community’s pick for everything except the Demon side; the Serpent variant trades one point of flat damage for a better damage multiplier, and players split on which actually wins at endgame. Weapon tiers T1-T3 are worth roughly +60% damage across the span, with a +10 refinement cap per tier (community-measured).

FAQ

How many weapons are in Slayers 2 at launch?

Officially 10 (7 Demon + 3 Slayer). Documentation names 12 — the gap is tracked openly in our database rather than papered over.

What’s the best early weapon to farm?

Rengoku’s Flame Katana: a repeatable boss, a weapon that upgrades into the Volcanic Katana, and a short horse ride from the central line.

How do I craft the shotgun?

Get the schematic from the Final Selection instance’s underground NPC (around 5%), then bring ~100 metal scraps, silk thread and 25,000 Wen to the blacksmith.

Does the Lost Shotgun still exist?

Yes — the September 19 hotfix made it obtainable after launch-day reports that it was unobtainable.
