Dr. Kobold's Wacky Wednesday

Dr. Kobold has dreams too but oh no this one is a nightmare!!! All hostile creatures that you can see and can see you must make a DC 19 Wisdom saving throw or take 5d10 psychic damage as visons of eldritch horrors taunt and torment them leaving them paralyzed for one minute. The targets can make additional attempts at succeeding the saving throw but should they fail it they will take the damage from the spell all over again  after each failed attempt. Should the caster be able to concentrate for the whole one minute duration the spell is shattered and so is their minds as they have their intelligence AND wisdom scores lowered forever to 1. This effect can be cured with dispel curse but only if cast at a 5th level spell slot or higher.
