At level 6, your Defile Ground starts to foster new life. As a reaction when your Defile Ground does Necrotic damage to an enemy – who is not an Undead or Construct – you can summon a Blighted Sapling. This little fella can immediately attack and then obeys your commands. These last until you summon a new one, until you take a long rest, or until it reaches 0 hit points. You can only use this ability a number of times per day equal to your Proficiency modifier.
