Revision 1

Deltras is the final boss of Snowfield of Sorrow, the Chapter 1. Lands of Sand and Snow Sanctuary raid that opened on the Korean and Taiwanese service on September 9, 2026. His title in the game is Storm Legion Commander. The Korean name is 델트라스.

Story

Deltras was once a hero and guardian of Elysium. After he was executed in Asmodae he became a thought-form, trapped in a mental space of his own making where he relives the same tragedy. Haunted by memories of battle and betrayal that will not fade, his body is driven by a corrupted will that curses and destroys everything. He absorbs negative energy, and when his power peaks he will cross into the real world to destroy Asmodae. The Elyos want to bring their hero peace and the Asmodians want to stop the destruction of Morheim, so both work with his daughter Elpistera to stop his body.

The Encounter

Deltras is fought after the middle boss Triton by a ten-player force. The raid runs on a temperature gauge, and frozen players are pulled to safety with ropes. Before the final arena the raid has to find Deltras's swords to break an ice barrier. In September 2026 the Korean service fixed several of his skills, including a binding freeze that could leave its target open to other attacks, and made the purple ice crystals in one of his patterns easier to read for colour-blind players without changing their hit areas. On September 16, 2026 his health on Easy was cut by 10%.

Records and Rewards

The first-clear event and the Sanctuary Hall of Fame are both measured by the time Deltras dies. The Hall of Fame keeps the first three Hard kills across all servers. Deltras's Seal, for the Seal equipment slot introduced with the raid, comes from this fight.
