Weaken Armor

With a whispered incantation, you warp and weaken the armor of a creature within range. Choose one creature you can see within range. The target must make a Dexterity saving throw. On a failed save, its AC is reduced by 2 (to a minimum AC of 10) for the duration. This reduction applies only to the target’s worn or natural armor and does not affect magical shields or spells such as Shield of Faith.

At the end of each of its turns, the target can make a Constitution saving throw, ending the effect on a success.

At Higher Levels. When you cast this spell using a spell slot of 2rd level or higher, the AC reduction increases by 1 for every two slot levels above 2nd.
