Violent Regrowth

Upon casting, the target's muscles spasm violently as new sinew begins to grow. The target is healed for 2d12, but is forced to do a DC 10 Constitution saving throw. If the target fails this saving throw, their body reacts violently to the sudden healing and they have disadvantage on attacks until the end of their next turn.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the healing increases by 1d12 for each slot level above 2nd and the DC of the saving throw increases by 3.
