Please note unknown is the actual description

This ring provides a moderately high HP and MP bonus along with a small SPD boost. Wear a more specialized ring if you do not need the balanced stats.

While at a glance this rings seems viable, it is entirely outclassed by significantly more common and attainable options, including the Ring of Decades or the Bracer of the Guardian, depending on which stats boosts you’re after.

When compared to the Ring of Decades, you sacrifice 110 HP for just 80 MP and 4 SPD. Simply put, if this was a good trade, then the Ring of Unbound Magic would be a viable ring, which it is arguably not.

When compared to Bracer of the Guardian, you sacrifice 6 defense and 6 attack for 20 HP, 20 MP and 4 speed, the defense adding a significant bulk increase over the 20 HP, and the 6 attack offering a considerable dps increase, arguably more impactful than 4 speed and 20 MP.

Interestingly, wearing it with the rest of the Void Archer set negates the speed penalties from the Armor/Quiver.
