History of Renunciation

Renunciation is an Exotic Jumpship, a ship rather than an ability or mechanic. It is listed as a Reef-built Ceres Galliot with an NLS Drive, and it was introduced with Episode: Revenant.

Sources differ on how to get it. Destinypedia links it to Kell's Vengeance, the Master-level version of the Tomb of Elders epilogue, where defeating Skolas opens a treasure room that awards the ship on its first clear. The D2 Wiki instead ties it to Episode: Revenant seasonal activities. Neither source lists any perks or special effects for the ship.
