Curse of Withering Limbs

Choose one creature within sight. Then chose a limb. The target must make a DC 17 Wisdom Saving Throw, or else suffer the effects of the spell. That limb withers and after one year the limb withers away and became useless. The only way to end the spell is if it is dispelled by Dispel Magic, or if Remove Curse is casted on the target. However, if the target succeeds the succeeds the saving throw, then the caster of the spell must take 2d10 necrotic damage and suffer a consequence appropriate. If the caster selected an arm, then the caster must drop what they are holding. If a leg was selected, then the caster falls prone, and must use an action to get up on their next turn.
