I just got my hands on this ilvl 825 trinket, and according to the Disc guide thread it's supposed to be quite good.
The tooltip says it does 146,654 damage to all enemies in a line, but it's only doing about 28,000 for me on a single target, which is pretty poor.
Is anyone else sharing this experience?
It appears that Corrupted Starlight is also doing really low damage.
