Disorient

Upon casting, choose a target. The target must make a Wisdom saving throw of 15. If the target fails, the target suddenly sees everything upside down, they feel dizzy and lose their balance. They must make a Dexterity saving throw of 10 or fall prone. While disoriented, each attack the target makes is at disadvantage, any acrobatic action is done at disadvantage, the target may move in a random direction instead of their intended direction (to be decided with a d2/coin toss, on a 1/tails they move in a random direction), and each spell cast with a somatic component has a 50% chance of failing (to be decided with a d2/coin toss, a 1/tails is a failure). They can make a new Wisdom saving throw each turn to break the effect.
