Shrivel

3rd-level transmutation

Casting Time: 1 action

Range: 30 feet

Components: V, S, M (exotic salts)

Duration: Concentration, up to 10 minutes You cause a creature to suddenly shrink, although anything it is wearing or carrying is not affected. Choose a creature other than a construct that you can see. It makes a Constitution saving throw. On a successful save, the spell has no effect. On a failed save, the target’s size is halved in all dimensions, and its weight is reduced to one-eighth of normal. This reduction decreases its size by one category—from Medium to Small, for example. Until the spell ends, the target also has disadvantage on Strength checks, Strength saving throws, and Strength-based attack rolls. The shriveled creature’s speed is halved and it has disadvantage on all attack rolls and Dexterity checks due to tangling in its clothing or armor until they are removed (at which point it regains its normal speed). The creature’s carrying capacity is reduced by half.

If you maintain concentration on this spell for the full 10 minutes, the duration becomes permanent and the spell’s effects last until dispelled.
