Sealing Strike (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Components:||V, S, M (a ranged weapon)|
When you cast this spell, you may make one weapon attack against a creature with a ranged weapon. On a successful hit, the ammunition transforms into a spear of light (or darkness) embedded into the creature, stunning it for 1 minute. If the creature takes damage, is moved, or another creature removes the spear, the effect ends. This ability fails if used on a creature of the same moral alignment. The creature must make a Strength Saving Throw at the beginning of each of their turns. Creatures that are Huge or larger gain Advantage on this Saving Throw. On a success, the effect ends.
