Visir’s Solemn Vow

This spell is cast by having two creatures opposite each other and clasping right hands. The caster will ask a certain number of vows of the other, with the second accepting those terms. Alternatively, the second creature can ask a certain number of vows, with the caster accepting those terms.

A thin tongue of brilliant flame issued from the casters hand and wound its way around their hands like a red-hot wire, weaving around the hands of the pair taking the vows.

When the creature who has accepted terms has broken a vow, the direction in which the creature who has broken the vow is always known to the other creature.

Additionally. the creature who has broken a vow will be cursed with the following effects: 

• While cursed, the target has disadvantage on Ability Checks and Saving Throws. 
  
  
• While cursed, the target has disadvantage on Attack rolls.

• While cursed, the target must make a Wisdom saving throw at the start of each of its turns. If it fails, it wastes its action that turn doing nothing.

The individual whom the vow was promised to can end the spell early by using an action to dismiss it. A remove curse or greater restoration spell can remove the curse effects of this spell. But only a wish spell can undo the vow and stop the tracking of the creature who broke it.
