Weaken the Flesh

You invoke the power of your diety and drain the targets life force. Tendrils of dark energy erupt from your hand and fly towards the target. The targeted creature must make a Condition saving throw. On a failed save, a target takes 1d10 necrotic damage and loses 10.ft movement. On a successful save, the creature takes half damage, but suffers no other effect. 

At Higher Levels. This spell's damage increases by 1d10 when you reach 3rd level (2d10), 5th level (3d10), and 7th level (4d10).
