Tharenisis' Hourglass of Horror

You summon before you an illusory hourglass of arcane energy, the magical sands within sift from the upper chamber into the lower, each grain of sand emitting a puff of purple smoke upon landing. Those who witness the hourglass are soon overcome with a sense of urgency and feelings of dread.

All creatures of you're choosing that are within sight of you, must make a wisdom saving throw or suffer the spells effects. Creatures who succeed at their wisdom saving throw disbelieve the illusory hourglass and cannot be affected again by the hourglass for the remaining duration of the spell. Creatures that fail their saving throw automatically suffer disadvantage on all attack rolls and wisdom saving throws as their minds are overwhelmed with thoughts of their own impending doom.

Additionally, you can choose to use an action on your turn to inflict 2d10 psychic damage to all targets currently affected by the hourglass; by forcefully flooding their minds with visions of their own death. Creatures who take damage in this way can immediately make an additional wisdom saving throw, with disadvantage, to disbelieve the illusion.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d10 for each slot level above 5th.
