Third eye

When you cast this spell you become omniscient for the duration and you may ask the DM any number of questions and they must answer them honestly. However, after you have asked the first question you must succeed on a DC 10 Wisdom saving throw. If you fail you take 10d10 psychic damage and the spell ends immediately. When the spell ends you are no longer omniscient and you only keep the knowledge of the answers to the questions you asked. Furthermore, due to the severity of this loss, you become temporarily mad for 3 hours. while you are mad you lose control of your character and the DM gains control of your characters actions. Additionally, you gain a new flaw and you cannot cast this spell again for 7 days.
