The Nightfall Katana is not sold by any weapon vendor in Slayers 2. Rays, the sword merchant, only stocks regular and fancy swords, so the only way into the Nightfall line is to find the schematic yourself and forge the blade later. It sits in a sealed ice cave beneath the waterfalls just outside Mistfall Harbor, and picking it up takes about a minute once you know the swim route.
Quick answer: Teleport to the Mistfall Harbor Shrine, drop off the cliff into the water past the docks, swim east under the waterfall into the hidden cave, climb the ledge, and press T on the frozen katana.
Nightfall Katana Schematic: Location and item details
The pickup is an ice-encased sword on a stone pedestal, labelled Nightfall Katana Study in the interaction prompt. It sits inside a cave that can only be reached by swimming, in the Slayers Crossing area south of Mistfall Harbor, underneath the log bridge that spans the waterfall.
| Detail | Value |
|---|---|
| Item | Nightfall Katana Schematic |
| Rarity | Mythic |
| Region | Head south from Mistfall Harbor to reach Slayers Crossing. |
| Interaction | Press T at the Nightfall Katana Study pedestal |
The item description reads: “Plans for a long blade, inked so dark the edge can only be found by tilting the page.” There is no puzzle, no boss and no key involved, which makes this the fastest of the Nightfall schematics to collect.

Switch to first person while swimming. Visibility under the waterfall is poor in third person and it is easy to overshoot the tunnel mouth.

How to confirm the schematic is in your inventory
Open the menu, select Shop, then Inventory, and switch to the Schematics tab. The Nightfall Katana Schematic should be listed there with a Mythic tag and the description about the dark-inked blade plans. If the tab is empty, you did not land the interaction and need to return to the pedestal and press T again.
Schematics are account-side items, so once it registers you can leave the cave freely. The quickest exit is to jump back into the cave pool and swim out through the same tunnel; climbing the rock walls back up to the log above the waterfall also works if you want to return to the harbor on foot.

What the schematic unlocks next
Holding the schematic does not give you the weapon. It unlocks the recipe, and you still need the crafting materials to forge it, with Mythic refinement ores used on the V2 and Nightfall line. Gather those before heading to a forge so you are not making a second trip.
The Nightfall Katana is one of seven Nightfall schematics scattered across the map, and each one uses a different method. The Claws sit underwater near the Yeti spawn, the Scythe is hidden in a cave under the Wind Breathing Trainer’s platform, and the Sickle requires pulling all ten hidden levers before its door opens. The Katana is the one worth grabbing first, simply because the route is short and nothing gates it.
