You get more items like that with high luck. It has no LMC, only 6 Stamina, no Dex, a resist is 2.
It could be used as a starter piece on a Warrior.
I would not save it. Britches of warding are better for that spot.
The RNG determines which stats the items gets and the range is determined by the name at the bottom.
If you are asking why it is Cursed. The stats could possibly be higher than a Brittle Major Artifact.
That looks equal to or better than Brittle Legendary Artifacts.
If you want a potion that removes something. I would go with Antique. I see a lot of better Antique items than I see cursed.
Cursed and Antique can have more or higher stats than brittle at the same level.
So, to get fat loot you get a lot of the fattest loot which is often cursed or Antique.
You can find Antique jewelry with a lot of maxxed stats.
