Ring of Noxtra
Carved from a thick band of semi-translucent obsidian, the ring of Noxtra is ice cold to the touch. Gracefully scripted runes flare with a mesmerising brilliance atop the surface of this artefact ring, and shifting shadow undulates about points of dazzling light. The night-hued ring is named for the destroyed planetoid Noxtra. It amplifies the effectiveness of a mana elixir by one tenth, allowing its bearer to regain more mana with each sip of said remedy. It is the least powerful of the triumvirate of rings with this power.
Two rings of Noxtra, along with two rings each of the Somnustra and Lunastra varieties, were gifted to some adventurers during the War of the Underworld before becoming available to the entire public for purchase. They are also sold by the artefact merchant Merentesh at The Statistic-Altering and Regeneration Artefact Shop in Delos.
