Ray of Clumsiness

A beam of wavering orange energy shoots from the caster's fingers towards a creature within range. A ranged spell attack must be made; on a hit, the target's muscles stiffen and their joints lock. Wherever it walks is treated as difficult terrain for it and it has disadvantage on all Dexterity checks, as well as Strength (Athletics) checks until the spell ends.

At the end of each of its turns, the create may make a Constitution saving throw to end the spell.
