You point at a target, and magical spikes appear on their body. The Target must make constitution saving throw, and if they fail, the spikes plunge into the target. Every turn the target must make another constitution saving throw, and if they fail, they are dealt more damage. The formula for caculating damage is: (Turn # X Spell LVL)

This ends either if the target succeeds a constitution saving throw, or they fail 6 times, in which the turn ends.
