Curse of the oracle

You touch a creature and bestow a limited ability to see into the immediate future, with a price. The creature must make wisdom saving throws at the start of its turn. On three successes, the creature can see into the future unlimitedly and has advantage on all saving throws and attack rolls. On three failures, it is permanently driven insane and gibbers its distorted visions constantly, becoming incapacitated. It is driven insane in this way until remove curse or a similar spell ends the curse, removing the insanity and the ability to see the future.
