Activate 
command
Effect You attempt to make the ring cast an arcane Wish spell. However, if the ring doesn't deem the wish to be sufficiently selfless, the wish isn't cast and the ring can't be activated for 24 hours.
You are Drained 3, whether or not the ring refuses the wish.
Once the wish is cast, the Ring of Recalcitrant Wishes has no powers, though it is rumored that the wearer's death in an act of profound self-sacrifice restores the wish to the ring.
Traits
This rarity indicates that a rules element is very difficult to find in the game world. A rare feat, spell, item or the like is available to players only if the GM decides to include it in the game, typically through discovery during play. Creatures with this trait are rare. They typically can't be summoned. The DC of Recall Knowledge checks related to these creatures is increased by 5.
DivinationThe divination school of magic typically involves obtaining or transferring information, or predicting events.
InvestedA character can wear only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
