Desert Mirage

You create a illusion that takes root in the mind of each creature of your choice within range. The targets must make an Intelligence saving throw. On a failed save, the illusion takes root and is described as a windy dessert with weapons stuck to the ground, and where the sun never fully sets. This can only be perceived by the creatures affected by the spell, at the start of each creatures turn it suffers 5d10 psychic damage seeing the different weapons striking the creature. 

This spell has no effect on undead or constructs.

The illusion includes sound, temperature, and other stimuli, also evident only to the creature.

The target can use its action to make another Intelligence saving throw to try escape the illusion on its turn. The illusion breaks if the caster loses concentration or the affected creature gets hit by an attack outside from the illusion.

While a target is affected by the spell, the target treats the illusion as if it were real. The target rationalizes any illogical outcomes from interacting with the illusion. For example, a target attempting to touch/grab any off the weapons gets a cut from touching its sharp edge or proves to heavy to lift.
An affected target is so convinced of the illusion’s reality that it can even take damage from the illusion.  Each round before the creature takes it's action it suffers 5d10 psychic damage, the weapons lifts from the ground flying in to the creature hitting it.
