Serpent Soul (Orochimaru Inspired V2)

Level 3: The Power of the White Snake

Your body has been modified to mimic the physiology of a great serpent. You gain the following benefits: Soft Physique: Your limbs are unnaturally flexible. Your reach for melee spell attacks increases by 5 feet. Resilient Scales: Your skin is reinforced by a layer of fine, white scales. While you are not wearing armor, your AC equals 13 + your Dexterity modifier. Substitution (Shedding): When you take damage, you can use your Reaction to shed your skin and move up to 10 feet to an unoccupied space without provoking opportunity attacks. You take only half the damage from the triggering attack. You can use this a number of times equal to your Charisma modifier per Long Rest.

Level 6: Hidden Shadow Snake Hands

At 6th level, you can manifest snakes from your body to strike and bind foes. Snake Strike: As an action, you can spend 2 Sorcery Points to strike a creature within 15 feet. The target must succeed on a Strength saving throw against your Spell Save DC or be Restrained and take 2d8 piercing damage. Potent Venom: Spells you cast ignore resistance to Poison damage.

Level 14: White Snake True Form

At 14th level, you can reveal the true, monstrous form of the White Snake. As a bonus action, you transform into a Large white serpent for 1 minute or until you are incapacitated. While transformed: Serpentine Lunge: You gain a flying speed of 60 feet. Ophidian Empowerment: When you cast a spell that deals Poison or Necrotic damage, you can add your Charisma modifier to one damage roll of that spell.

Living Corpse Reincarnation

At 18th level, you have perfected the art of transferring your soul and regenerating your form. Death Evasion: When you are reduced to 0 hit points, you can immediately shed your skin (no reaction required) to drop to 1 hit point instead. You then immediately move up to 30 feet to an unoccupied space without provoking opportunity attacks. Once you use this feature, you cannot do so again until you finish a Long Rest. Eight Branches Jutsu: You can cast the Summon Dragon spell (2024) once per Long Rest without expending a spell slot or material components. When cast this way, the creature takes the form of a gargantuan eight-headed white serpent.
