Daborsk is a member of the lost crew. Once saved he upgrades angelic souls (Soul of the Frozen One, Soul of the Warden, Soul of the Saint Lord) in the Library.
Location[]
Upon leaving the Library on the north-western side (near the save point), he will be standing near the button outside.
Lore[]
No one knows exactly why this brilliant Alagathian mana weaver left the angelic army. He tends to avoid conflict, end everyone in the crew seems to be more relaxed when he's around.
