Ludleth of Courland or "Ludleth the Exiled", as his throne reads, is a Merchant in Dark Souls III. He is a Lord of Cinder and transposes weapons, equipment, and spells for the player.
Ludleth is a Lord of Cinder, having linked the flame prior to the events of the game. He is a practitioner of the dark art of Transposition. Little is known about his past, although it is implied on his throne that he was exiled from somewhere at some point.
After defeating the Curse-rotted Greatwood in the Undead Settlement, the player must give Ludleth the Transposing Kiln in order to transpose boss souls into various weapons equipment, and spells.
It is not necessary for the player to carry their acquired boss souls in their inventory in order to begin transposition. As long as the player has defeated a boss and obtained its soul, its available transpositions will appear in Ludleth's menu even if the soul has been placed in the storage box.
If Ludleth will dies, transposition of boss souls will still be available by interacting with his throne. If the player defeats the optional Curse-rotted Greatwood after Ludleth has died it will be impossible to give him the Transposing Kiln.
If the player brings Ludleth both Lorian's Greatsword and Lothric's Holy Sword, a new entry will appear when talked to, allowing to use both swords to forge the Twin Princes' Greatsword. This is only possible in NG+ as each weapon requires one Soul of the Twin Princes to be created, and only one can be obtained per playthrough.
