During this attack, the creature will move forward towards the victim. DM rolls a d20. If the outcome is <10, then the victim will take 12 damage and the Crimson Deroxine will be exactly 3 ft. in front of the victim. If the outcome is >10, then half of the victim's HP is removed, and Crimson Deroxine will be 20 ft. directly behind the victim.
