Daystar

Daystar is a unique steel sword in The Witcher 3: Wild Hunt.

It can be found as random loot in many places, but also guaranteed in the following:

from Abaya during Contract: Muire D'yaeblen
on a corpse in the chamber where the Nightwraith is during Peace Disturbed
on a corpse near, but not the actual guarded treasure on an island northwest of An Skellig, guarded by a Basilisk
on a corpse between the two eastern circles southeast of Arinbjorn, near the crypt where Diagram: Wolven silver sword - superior is found
on a corpse in one of the jail cells at Castle Tuirseach during Scavenger Hunt: Bear School Gear

Generally speaking, if you see a sitting corpse somewhere on Skellige, it likely has the sword.
