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

The Lost items are the hidden Mythic prizes in Slayers 2. Four armor pieces — the Lost Mask, Lost Outfit, Lost Cape, and Lost Lantern — plus a Shotgun Schematic all trace back to one secret boss and one fishing spot, and none of the armor pieces ever appear on the boss’s visible drop table. There are only two ways to pull them, and each has its own pace.

Quick answer: Kill The Lost Slayer in Final Selection for the Lost Chest, where each armor piece drops at 0.9%. Fishing at Mistfall Harbor pulls the same pieces plus the Shotgun Schematic.

Lost Set pieces and stats

All four items are Mythic rarity in the Technician class, and wearing them together lets their bonuses stack. Each one raises Additional Damage, making the complete set worth pursuing even without considering its trade value.

Piece	Additional DMG	Max Health	Max Stamina
Lost Mask	1.04x	+60	+50
Lost Outfit	1.01x	+95	+70
Lost Cape	1.03x	+45	—
Lost Lantern	1.03x	+45	+40

On top of those numbers, the pieces carry regen bonuses. The Mask and Lantern each add stamina regen, the Cape pushes stamina regen to 1.09x, and the Outfit brings 1.08x health regen alongside 1.05x stamina regen. The Lantern also adds a small illumination bonus that is genuinely useful inside the dark cave where the boss lives.

Farm The Lost Slayer boss in Final Selection

Farming the boss is the steadier way to obtain all four armor pieces. The key requirement is Final Selection: only human Slayers may enter. Demons must switch back before they can get in.

You need to be a human Slayer. A Demon can change race through the Shop’s Ore tab by paying 10 Ore.
The event becomes available at two-hour intervals, at each even-numbered hour.
The trial asks for level 45 minimum; solo runs are far easier near level 60.
Traveling west is much quicker on a horse, although walking works too.

Changing race through the Ore tab has the same effect as the paid Robux option, so spending Robux for a race change is unnecessary.

Use fast travel to reach the Butterfly Estate Shrine, then make your way to the Final Selection gate. Find the small platform occupied by the Sisters NPCs.

Wait atop the platform until the countdown reaches zero. When the even hour arrives, the Sisters send everyone standing there down into the trial.

Leave the spawn point and follow the dirt path directly west. Avoid the roaming demons; battling them wastes health needed for the boss. Continue until the path reaches a lake.

Head into the water and dive. An entrance in the rock on your left leads down into a sealed cave.

The drop puts you face-to-face with Lost — The Lost Slayer, who has 790 HP. After a kill, he returns in roughly a minute, letting you fight him repeatedly during the remaining trial window.

A Lost Chest appears after every kill. Each armor piece can drop from it at a 0.9% rate, so players regard the set as a secret drop rather than an ordinary Mythic. The only reward listed for the boss is the Shotgun Schematic, with a 5% drop rate. Long dry runs are possible; expect to use several trial windows to collect all four pieces.

Fish for the Lost items at Mistfall Harbor

Fishing reaches the same Lost items and is the only route that also pulls the Shotgun Schematic without a boss window. It is slower and rarer per catch, but it runs while you wait for the next even hour. The setup below maximizes bite speed and fishing luck.

Equip the Legendary Fishing Rod. It grants a 3x bite speed multiplier, +60 cast radius, the sunken-gear catch tier that reaches Lost items, and +0.775 Fish Luck.

Fit the right bait. Use the Rare bait Fish Head or the Legendary Golden Tentacle, not the Drowned Lure. Fish Head adds bite draw and a small luck bonus and is spent each time the line resolves.

Open the Titles menu and equip three fishing titles for the luck and bite-speed buffs.

Title	Requirement	Buff
Deep Water Angler	Catch 250 rare fish	1.05x Bite Speed
Legendary Fisherman	Inherit the drowned fisherman’s line	1.07x Luck, 1.05x Bite Speed
Salvager	Pull 25 lost items from water	1.08x Fishing Luck

Run an AFK fishing macro so the line recasts on its own. 1vtt’s open-source Project Slayers 2 fishing macro is the one most players use for long sessions.

Position your character on the high, dark rooftop ledge at Mistfall Harbor. The dark grey texture behind the fishing bar gives high contrast, so the macro reads the white target box accurately.

Left running, this setup pulls Shotgun Schematics, the Lost Mask, Lost Outfit, Lost Lantern, and Lost Cape, along with Mythic Ore and rare fish. Check your inventory between sessions to confirm what landed.

Get the Lost Shotgun

The Shotgun Schematic is water-stained plans clear enough for a gunsmith to copy. Bring it to the gunsmith to craft the shotgun. The Mythic Lost Shotgun is a separate weapon in the Duelist class — it is fished up or crafted at Ouwland, and the Lost Chest boss farm will not hand it to you no matter how long you loop.

The Lost Shotgun carries +15.75 Additional Damage, a 1.15x Additional Damage Factor, +7.85 Block Points, 2.29x Block Regen, and +45 Max Stamina, which sets it well above the base Legendary Shotgun’s +7 damage and +2.7 Block Points.

Trade the Lost Cape and Outfit for Nightfall and First Light

The Lost Cape and Lost Outfit can be used in trades as well as equipped. If you are aiming for higher-tier armor, focus on obtaining these two pieces and farm two copies of each: one for your character and one for trading.

After obtaining a Lost Cape, teleport to the Hidden Mist Village shrine, travel toward the Stone Sanctuary, and descend into the concealed area beneath it to reach Weaver Hatsu. He exchanges the cape for the Nightfall Cape Schematic. The Lost Outfit serves the same role in the First Light armor line. To get the Nightfall Top and Bottom schematics, visit the Blacksmith in Hidden Mist Village and choose “The Set Drawings” option; you must already have all nine Nightfall schematics.

Confirm a Lost drop landed

Since armor does not appear in the fight’s loot table, the item is the only way to confirm a drop. Once you open a Lost Chest, look through your inventory for Lost Lantern, Lost Cape, Lost Mask, or Lost Outfit. In the Archives, the entry identifies the piece as Mythic and Technician class, with its source listed as a 0.9% Lost Chest drop or fishing. Equipping it immediately updates your model, showing the gold horned mask, dark red cape, or lantern in hand.

Lost items collected during a Final Selection run remain in your inventory even if you do not pass. Failure does not take away drops you have earned, so continue farming the boss until you complete the set.
