School of Biomancy

Practitioners of biomancy tend to have a growth mindset and an endless propensity for self-improvement. You likely bear symptoms of this continual desire to improve yourself: patches of scales, manes of peacock feathers, hawk’s eyes, adhesive palms, gills… the list is as long as there are ideas to try. Biomancers are  masters of biomantically-enhanced surgery, transplanting specially-grown (or amputated) appendages ontoother creatures.

Biomancy Savant

Beginning when you select this school at 2nd level, the gold and time you must spend to copy a Biomancy spell into your spellbook is halved. In addition, you gain proficiency with Surgeon's Tools, and the following spells are considered biomancy spells for you instead of their normal school.

Biomancy Spells

Level	Spells
1st	False Life, Longstrider
2nd	Alter Self, Longstrider
3rd	Haste, Water Breathing
4th	Stoneskin
6th	Flesh to Stone
7th	Simulacrum
9th	Shapechange

Biostimulation

Starting at 2nd level, you learn to channel biomantic magic into your cells, restoring your vitality. When you use a spell slot to cast a biomancy spell of 1st  level or higher, you can simultaneously redirect a strand of the spell’s magic to energise and repair you or your target’s body. You or your target (your choice) regains a number of hit points equal to twice the spell’s level.

Self Improvement

At 6th level, you can perform minor surger yon your body, improving yourself in a very literal sense. Over the course of 1 hour (which can be done during a rest), you can enhance yourself with one bio-magical improvement, choosing from the following options:

• Amphibisprings. With enhanced quads and a ratcheting mechanism in your achilles, your jumping distance is tripled.
  
• Extra Appendage. You gain a prehensile tail or an extra arm, allowing you to hold one more thing and conferring advantage on any ability checks you make to climb.
  
• Detachable Hand. As an action, you can detach your hand and imbue it with biomantic magic. The hand follows the rules of the Unseen Servant spell, except it is not invisible and waits patiently if ever more than 60 feet away from you. If your hand is ever reduced to 0 hit points, it is destroyed, and you grow a new one over the course of a short or long rest.
  
• Firefly Skin. You can cast the Light cantrip at will with yourself as the target. As a bonus action, you can flash brightly for a moment; each creature within 5 feet of you that can see you must succeed on a Constitution saving throw against your wizard spell save DC or be blinded until the end of your next  turn. After you use this bonus action, you can’t do so again until you finish a short or long rest.
  
• Owl Eyes. You gain darkvision out to a range of 120 feet.
  
• Slime. You exude slime; checks made to grapple you have disadvantage.
  
• Scales. Your skin is covered in overlapping scales. You gain a +1 bonus to AC when you aren’t wearing armour.
  
• Spidersense. You gain a 1d4 bonus to your initiative rolls.
  
• Talon. One of your hands is replaced with a wicked giant hawk’s talon, a natural weapon that you can use to make unarmed strikes. If you hit with it, you deal slashing damage equal to 1d8 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike. If you are grappling a creature with this talon, you can automatically deal this damage to the grappled creature once on each of your turns as a bonus action.
  
• Third Leg. Your speed increases by 10 feet and you have advantage on ability checks and saving throws made against effects that would knock you prone.
  
• Trimorphism. You can cast the Enlarge/Reduce spell on yourself at will (no material components or concentration required).
  
  

Your body has enough latent biomantic magic to sustain one improvement at a time. When you reach 10th and 14th level, you can sustain up to two and  three improvements at a time, respectively. If you gain a new improvement while you have your maximum number of sustainable improvements active, you  must choose one improvement to lose; this improvement withers away and ceases to function the moment you finish the surgery on your new improvement.

Spell Splitter

At 10th level, your fiddling self-improvement has led to the ability to benefit from the magic you create. When you cast a wizard spell that targets only one creature and doesn’t have a range of self, you can choose to simultaneously target yourself with the same spell. You can use this feature a number of times equal to your Intelligence modifier (minimum once), regaining all expended uses when you finish a long rest.

Endocrine Overload

When you reach 14th level, over the course of 1 hour (which can be done during a rest), you can craft a capsule of potent stimulants, choosing from either  the Brutish or Swift archetypes, and embed it within your adrenal gland. With a slight tensing of your brain muscles, you can crack this capsule as a bonus  action, stimulating your body. For the next minute, you gain the following benefits based on the archetype you chose:

Brutish

• If you are smaller than Large, you become Large, and your weight increases proportionately. If you lack the room to become Large, your size doesn’t change.
  
• Your Strength score increases to match your Intelligence score if it isn’t already higher.
  
• You have advantage on Strength and Constitution checks and Strength and Constitution saving throws.
  
• You grow an appendage with which you can make melee weapon attacks. When you grow the weapon, you decide whether it deals bludgeoning, piercing, or slashing damage. You are proficient with this weapon and use your Strength modifier for attack and damage rolls. The weapon deals 2d10 damage.
  
• You can attack twice, instead of once, when you take the Attack action on your turn. You ignore this benefit if you already have a feature, like Extra Attack, that lets you attack more than once when you take the Attack action on your turn.
  
• You gain temporary hit points equal to twice your Intelligence modifier (minimum of 2) atthe start of each of your turns.

Swift

• Your Dexterity score increases to match your Intelligence score if it isn’t already higher.
• You have advantage on Dexterity checks and saving throws.
• Your cantrips with a casting time of 1 action have a casting time of 1 action or 1 bonus action.
• You gain the benefits of the Haste spell, which can’t be dispelled:
  • Your speed is doubled.
  • You gain a +2 bonus to AC.
  • You can take one additional action on each of your turns, which can be used only to take the Attack (one weapon attack only), Dash, Disengage, Hide, or Use an Object action.

Relapse. When the minute elapses, you gain one level of exhaustion, and you can’t move or take actions until the end of your next turn, as a wave of lethargy sweeps over you. You must craft another capsule before you can use this feature again.
