Ring of Somnustra
Fashioned from threads of muted white gold, the ring of Somnustra is dominated by a single, circular amethyst set in its centre. Surrounding this unassuming band is a fog-like shroud which acts to conceal the ring almost entirely from sight. The ring has the power to intensify the restorative properties of the mana elixir by a fifth, allowing its wearer to regain more mana with each sip of that potion.
Rings of Somnustra, along with two rings each of the Noxtra 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 sold by the artefact merchant Merentesh at the Statistic-Altering and Regeneration Artefact Shop in Delos.
