You can use an action to utter a curse. The curse targets another creature within 30 feet that the caster can see. The caster can’t utter another such curse before finishing a long rest.

The curse is a repayment for an injustice or a slight. The target must succeed on a Wisdom saving throw to avoid the curse. The saving throw DC is 8 + the caster's proficiency bonus + the caster’s Charisma modifier. The curse lasts until ended with a remove curse, spell, a greater restoration spell, or similar. It doesn’t end when the target dies. If a cursed target is returned to life, the curse remains in effect.

When the curse ends, the caster suffers a harmful psychic backlash. The amount of this psychic damage depends on the severity of the curse that was invoked.

The caster chooses the curse’s effect from the options that follow; other curses may be used at the DM's discretion. All such effects deal psychic damage to the caster who uttered them when they end:

• The target is unable to perform a certain kind of act involving fine motor control, such as tying knots, writing, playing an instrument, sewing, or casting spells that have somatic components. When this curse ends, the caster takes 3d6 psychic damage.
• The target’s appearance changes in a sinister yet purely cosmetic way. For example, the curse can place a scar on the target’s face, turn the target’s teeth into yellow fangs, or give the target bad breath. When this curse ends, the caster it takes 2d6 psychic damage.
• A nonmagical item in the target’s possession (chosen by the DM) disappears and can’t be found until the curse ends. The lost item can weigh no more than 1 pound. When this curse ends, the caster takes 1d6 psychic damage.
• The target gains vulnerability to a damage type of the caster's choice. When this curse ends, the caster takes 6d6 psychic damage.
• The target has disadvantage on ability checks and saving throws tied to one ability score of the caster's choice. When this curse ends, the caster takes 5d6 psychic damage.
• The target’s attunement to one magic item (chosen by the DM) ends, and the target can’t attune to the chosen item until the curse ends. When this curse ends, the caster takes 5d6 psychic damage.
• The target is blinded, deafened, or both. When this curse ends, the Vistana takes 6d6 psychic damage.
