Bilburglow's Trivial Trivia

Ask a creature of your choice that you can see within range an enchanted trivia question. The target must succeed on an intelligence save or the creatures mind becomes clouded and the creature becomes obsessed with trying to figure out the answer to your question. While pondering the answer to your question the creature is stunned. A creature with an intelligence score of 4 or less is unaffected and the creature must know at least one language, which does not have to be one that you speak. The creature rerolls its save at the start of its turn or if it takes damage, the creature has advantage on its saving throw if it takes damage.

When upcast you may target one additional creature per spell level above 3rd.
