Ring of Mixed-up spells

The Identify spell will incorrectly identify this ring as a Ring of Spell Storing that provides an extra attunement slot.

This is a cursed item and a frequent byproduct of a failed crafting. When attuned and all attunement slots are filled, this will push out the last attuned magic item. When the user attempts to cast a spell, the spell title is changed into something that sounds similar with effects at the DM's discretion. (Examples: "Shield" becomes "Yield" or "Field" which can allow the projectile attack to pass through or magically sprout a grassy field nearby; "Magic Missle" become "Magic Whistle" which can summon a strange and fantastic beast; etc)
