A sword once carried by Harrower Dervla of the Dark Crusaders.
Hidden lore — revealed in game at high Radiance
Increasingly plagued by doubt and regret over her choices and the cause of the Dark Crusaders as a whole, Dervla felt lost and alone - until the day she descended to the base of Sunless Skein, and discovered purpose and companionship anew.
Harrower Dervla was a Dark Crusader, which is why her sword and her crossbow share the order's name.

Set bonus — Harrower Dervla’s Sword
This weapon is tagged as part of a set in the game files, which means equipping it with the rest grants something. What that something is has not been read out of the ability data yet, so it is listed rather than described.
The only weapon in its set — the bonus is on the weapon itself rather than on a pairing.
What it takes
Meet the weapon's stat requirements and the special attack is available — at any upgrade level, with no quest to finish first.
Set membership is read from the weapon's own ItemTags in the game files.
Unlock conditions were removed by patch 2.5.593 on 15 August 2026; before it, several
of these were gated behind questlines. The game itself never mentions any of this.
