Slayers 2: How to Get the Full Lost Mythic Set (All Four Pieces)

The Lost set is the quiet prize of Slayers 2. Four Mythic pieces — the Lost Mask, Lost Outfit, Lost Cape, and Lost Lantern — all come from one boss tucked inside a cave you can only reach during Final Selection, and none of them show up on that boss’s visible loot table. They also gate the Nightfall and First Light armor paths, which is why players who have never touched the trial suddenly need to.

Quick answer: Enter Final Selection as a human Slayer, ride west from spawn to the lake, dive into the underwater cave, and kill Lost — The Lost Slayer repeatedly. Each piece drops at 0.9%.

Requirements before you start farming the Lost set

Everything about this farm hinges on one gate: Final Selection only lets human Slayers in. If you took the Demon path, you cannot walk through the door, full stop.

Be a human Slayer. Demons can reset their race in the Shop’s Ore tab for 10 Ore.
Final Selection opens every two hours, on the even hour.
The trial asks for level 45 as a minimum, and solo runs are far more comfortable closer to level 60.
A horse makes the run west much faster, though you can do it on foot.

Two codes currently work: Release26 and SkillTreeReset. Together, they grant spins, Wen, one Refinement Ore, and a skill point reset. Before redeeming either code, the account you use must join the Ouw Productions Roblox group. After joining, enter the codes in the field along the lower edge of the screen and choose Redeem.

Resetting race through the Shop’s Ore tab costs the same 10 Ore and does the same job as the paid developer product, so there is no reason to spend Robux on it.

How to reach the Lost Slayer boss in Final Selection

Fast travel to the Butterfly Estate Shrine and head toward the Final Selection gate. Look for the small platform where the Sisters NPCs stand.

Stand on the platform and wait for the countdown to hit zero. On the even hour, the Sisters teleport everyone on the platform down into the trial.

From the spawn point, travel straight west along the dirt path. Ignore the wandering enemies — fighting them only burns health you will want for the boss. Keep going until the ground opens onto a lake.

Swim out and dive underwater. On the left side there is an opening in the rock that drops you into a sealed cave.

Drop in and you are standing in front of Lost — The Lost Slayer, a boss with 790 HP. He respawns roughly a minute after each kill, so you can sit in the cave and loop him for the rest of the trial window.

Lost Chest drop rates and how the secret drops work

Killing Lost spawns a Lost Chest. Each of the four armor pieces has its own 0.9% chance to appear from that chest, and none of them are listed on the boss’s drop table during the fight — that is why players call the set a secret drop rather than a normal Mythic. The visible reward is a Shotgun Schematic at 5%.

There is no shortcut around the percentage. Expect long stretches with nothing, and plan on multiple trial windows before all four pieces land. Fishing is the only alternative route to the same items, and it is slower and rarer than farming the boss, so treat it as something you do while waiting for the next even hour rather than a real strategy.

The Lost Shotgun is not part of this farm. Despite the name, Lost does not drop it — it is crafted at Ouwland or fished up.

Lost set stats for all four pieces

Piece	Additional DMG Factor	Max Health	Max Stamina
Lost Mask	1.04x	+60	—
Lost Outfit	1.01x	+95	+70
Lost Cape	1.03x	+45	—
Lost Lantern	1.03x	+45	+40

All four pieces are Mythic rarity and sit in the Technician class, so they stack cleanly as a set. On top of the numbers above, the Mask adds 1.04x stamina regen speed, the Cape pushes stamina regen to 1.09x, the Outfit carries 1.08x health regen plus 1.05x stamina regen, and the Lantern adds 1.01x health regen, 1.03x stamina regen, and a small illumination bonus that is genuinely useful inside dark caves.

What the Lost set unlocks: Nightfall and First Light

The Lost Cape and Lost Outfit are trade materials, not just gear. Once you have the Lost Cape, teleport to the Hidden Mist Village shrine, head toward the Stone Sanctuary, and drop into the hidden area below it to find Weaver Hatsu. Hand over the cape and he trades you the Nightfall Cape Schematic. The Lost pieces feed the First Light armor line the same way.

The Nightfall Top and Bottom schematics come from the Blacksmith in Hidden Mist Village, under the “The Set Drawings” dialogue option. He only hands them over once you hold all nine Nightfall schematics, which means every Nightfall weapon schematic has to be done before the armor path opens.

Nightfall weapon schematics you need first

Two of them are the usual bottlenecks. The Serpent Katana needs a Serpent Key that spawns on the seabed near Mistfall Harbor, and it often takes several dives before one appears.

With the key in hand, ride into the nearby cave and open the Serpent Box to claim the schematic.

The Gauntlet schematic starts with Stonemason Tobei in the Hidden Mist Village workshop, who sends you to wake three statues — 100 hits each, with the third requiring bare fists — before he hands it over.

How to confirm a Lost piece actually dropped

Because the pieces never appear on the fight’s loot table, the only confirmation is the item itself. After opening the Lost Chest, check your inventory for a new entry named Lost Mask, Lost Outfit, Lost Cape, or Lost Lantern. Open the Archives and the piece will be listed as Mythic, Technician class, with its source shown as the 0.9% Lost Chest or fished up.

Equip it and the model changes immediately — the gold horned mask, the dark red cape, the lantern in hand. Once all four are on, the stat bonuses stack and the set is done. From there it is just a question of whether you want to keep wearing it or hand the cape to Weaver Hatsu and start the Nightfall grind.
