| Shellreaper floor, chance and upgrade recipe | 1 source |
King Legacy dungeon rewards belong to a particular dungeon, difficulty and floor. For Shellreaper, the community wiki identifies Hard Dungeon at Land of Detention in the Third Sea, with Craberno on floor five as the relevant encounter. Follow that named route rather than treating every dungeon entrance or every final boss as an interchangeable source of the sword.
The Shellreaper page lists an approximately 0.1 percent drop chance. That is a chance attached to the listed reward, rather than a promise that a fixed number of clears awards the weapon. A short streak without the sword does not establish that its location changed. Compare the dungeon name, difficulty and enemy before changing your farming route.
Acquisition and upgrading are separate projects. The first upgrade recipe lists twenty Voltix, one Shadow Lure, fifteen Crustar, five Crab Meat, one hundred Coral and one hundred Sea Artifact. The later recipes retain the first three ingredients while increasing Crab Meat, Coral and Sea Artifact. Keep these materials separate from the question of where the sword initially drops.
Shellreaper is listed as untradeable, so a trade listing is not an alternative to its dungeon route. If your objective is another weapon, start with that weapon’s obtainment field and work backward to the required activity. Our practical recommendation is to choose the target reward first, then prepare a build for reaching its specific floor consistently. A general dungeon speed claim does not prove that it includes the correct difficulty, eligibility conditions or loot table. The linked Shellreaper source supports this route; it does not supply a complete reward catalogue for every dungeon.
