Canthony's Dark Connection

You channel dark energy into the ground, manifesting roots that claw at nearby targets. When casting this spell, you must first make a Charisma saving throw. On a success, all targets of your choice within 30 ft. must make a Constitution saving throw. Each target that fails takes 3d8 necrotic damage, and you are healed for half of the total amount of damage dealt. If you fail the Charisma saving throw, the spell affects all creatures within 30 ft., rather than just those of your choice.

At Higher Levels. The damage from this spell increases by 1d8 for each spell level above 5th.
