Defeat Lost in Final Selection’s hidden underwater arena and open Lost Chests until you collect the Lost Mask, Lost Outfit, Lost Cape, and Lost Lantern.
You can get the Mythic Lost Set in Slayers 2, but you can farm its pieces only inside Final Selection. Defeat Lost and a Lost Chest appears. Lost’s loot goes beyond the displayed rewards, so don’t let the drop-rate listing throw you off: it doesn’t identify the secret drops.
Lost Set pieces, drop chances, and stats

All four pieces have Mythic rarity and belong to Technician Class. Together, they make up the boss-farmed equipment set. You can view each component and its stats through the Archives tab in your inventory, where weapon schematics also appear.
Reach The Lost Slayer in Final Selection
Before setting out, budget 10 Ore if you need the Shop’s Reset Race purchase. Resetting retains your character’s progress.
Reaching the entrance is only part of getting inside: Final Selection has a scheduled entry window.
For preparation rewards and resets, you can also try RELEASE26 and SKILLTREERESET through the in-game code menu, if they’re still active.

Fight the boss labeled The Lost Slayer / Lost and deplete its 790 HP. Its displayed reward is Shotgun Schematic x1 (5%), separate from the equipment drops.
STEP 9/9

Open Lost Chests and repeat
Defeating Lost produces a Lost Chest; open it for your rewards, which can also include Wen and metal scraps. Fight subsequent spawns and open their chests until you own every equipment piece in the set.
Spare armor trades and the Lost Shotgun
Hold onto your Lost Cape and Lost Outfit if you’re after Nightfall and First Light schematics: some require you to trade those armor pieces. They’re useful beyond wearing them, so keep the trades in mind when sorting your drops.
For the Lost Shotgun, go fishing or craft it at Ouwland. The boss doesn’t drop it. Its Archives entry lists it as Impossible / Mythic and assigns it to Duelist Class, while the regular Shotgun is a Legendary weapon. The Lost Slayer’s listed drops include Shotgun Schematic x1.
When you’re farming for those later trades, aim for two Lost Capes and two Lost Outfits so you have spares. That’s a suggested amount to collect.
