It seems like quite a few of the "named" magic items I've run across so far (out of about a dozen) are cursed in some way. Even the reward that the druids get you for rescuing Halsin is cursed, and deals damage to the player when you wield it.
It just feels a bit excessive to have half the named items in the game not be worth using because of the negative effects.
Sorrow's description mention it deals damage to the wielder at least.
There is a spear with the text description that it will grant you advantage on your next attack after a miss (aka true strike), instead it grant true strike (permanently it seems) to the enemies that you successfully hit.
But yeah, a lots seems worthless, maybe they just exist to feed Gale.
