Ring , very rare
This silver and ruby ring is inscribed with sigils of an ancient High Magic, allowing the attuned wearer to apply meta-magic feats bound within the ring to spells they cast.
The ring has three high magics available to the wearer at a time from the feats bound within it; Careful, Distant, Empowered, Extended, Heightened, Quickened, Subtle, and Twinned. The three feats may be changed after a long rest.
The ring also contains 5 high magic points within it, that are used when casting spells with the meta-magics applied. These points return after a long rest. Once they are spent, the spellcaster may use their own sp to activate the High Magic. The sp in the ring can not be used to convert spell slots to sp or sp to spell slots.
