**Perk: **When you drink a potion, you have a 50% chance to recycle it via whatever orifice you prefer. You have 10 minutes to excrete the potion. You start with two black thumb rings (the secret mark of your profession) and a random potion.

**Drawback: **Whenever you receive magical healing, Save or gain a mutation. The regeneration spell does not trigger this.

1. Transfer a blemish or cosmetic feature from one creature to another. You could swap eye colours with an elf or pull warts off a toad and put them on a princess. You cannot transfer significant effects (poison glands, wings, etc..)
2. Taste blood to tell what kind of creature it came from.
3. If you wish, your appearance will no longer age. Once you activate this, you will always look the same age. This may fail in times of dire stress. The potion recycling perk is fairly useful, but your friends may not be willing to try the recycled potion. Magical healing is fairly rare in my setting so the drawback is less dangerous. The cantrips are a bit odd. If you'd like, roll 20+3d20 for your actual age.

1- Acid Arrow 2- Alter Self 3- Animate Potion 4- Extract Venom 5- Shrivel 6- Hand of the Hound 7- Infantilize 8- Monsterize 9- Regeneration 10- Blood Jelly

11- Wave of Mutilation 12- Mutate

R: 50' T: creature D: 0 Target takes [sum] damage, and [sum-4] damage over the next 2 turns unless washed.

R: 0 T: self D: [dice]x10 minutes Alter your form to resemble that of another creature of your type (usually humanoid.) You do not gain any special abilities from this transformation.

R: touch T: potion or liquid D: [sum] hours

You turn a potion into an obedient homunculus (HD 0.) It is tiny (1' tall) and feeble (Str 1), but it can go where you direct and even bring you small items (like a single coin.) The potion can be delivered by touch or by “drinking” the homunculus. Aware targets can swat the homunculus away to avoid the potion's effects. Works on any liquid except water.

R: touch T: creature D: 0

You pierce a creature with a sharp object and draw all of the venom out, which then pools in your hand or a vial. If you use this to remove the poison from a poisoned creature, that creature gets a new Save with a +4 bonus. You can also use this to draw all of the poison out of a venomous creature. Unwilling venomous creatures may Save to negate this effect. Most biomancers keep one of their fingernails razor sharp for this purpose.

R. 50' T: [dice] creatures D: 1d6 rounds / permanent

Save negates. Target loses half of its current HP and loses 6 Strength (affecting the damage it deals.) When the spell ends, the lost HP and Strength returns. If you cast this spell with 3 or more [dice] against a single target, the lost HP does not return, and the Strength damage is permanent. The apparent age of the target increases considerably for the spell's duration.

R. self T: one or both hands D: 10 minutes

Your hand falls off and grows into a monstrous version of itself: HD: [dice]

Attack [dice]+d10 Defense 14 Strength 16

You continue to control it, but if it dies, you don't have a hand anymore. Alternatively, you can have this affect both hands, but you’ll look quite foolish.

R: touch T: creature of [dice]x2 HD or less D: [sum] minutes

Target Saves or becomes an adorable, if slightly eerie, child version of itself. Creatures lose 1 HD (-6 max HP, -1 to hit, -1 to Save.) The target's Strength is reduced by 5. The target is now so adorable that all who see it must Save the first time they try to harm it or hesitate. If they fail this Save, they can act normally the next round.

R: touch T: creature with 0 HD (vermin) D: [sum] minutes

Target vermin (rat, scorpion, termite, etc) becomes huge and aggressive.

HD: [dice]x2 Attack: [dice]+d10 Defense: 12

Monstrified vermin attack the nearest foe, and casters usually throw the vermin as they cast this spell. Works on goblins and other low HD monsters. There is a 1-in-10 chance that this spell will be permanent. If you invest 4 [dice], the creature also mutates.

R: touch T: creature D: [dice] hours Target regenerates 1 HP every 10 minutes. If a sufficiently magical object (a troll heart, a unicorn horn, an aboleth eye, etc.) is used in the casting, target also regrows missing limbs or damaged organs.

R: touch T: meat (1 ration's worth) with some of your blood on it and the blood of up to [dice] other people D: permanent You touch dead meat or a pool of blood and create a tiny blood jelly. It starts as the size of a thimble. It's is transparent with a red spidery nucleus. It won't harm anyone who contributed blood to its creation.

The blood jelly will react the same way you do to any potions or items fed to it. It's a great guinea pig. If it stays small and you feed it an entire potion, you can consume it to also gain the potion's effect.

The more you feed a blood jelly, the larger it grows. They lose 10% of their weight each day, and gain 10% of whatever they eat in weight, and it takes an hour to eat something as big as they are. They have 1HD per doubling past 100 pounds and their default attack is sucking 1d4 points of blood per HD they have. Given 1000 pounds of meat, a fist-sized jelly takes about a day and a night to reach 100 pounds and 1HD. The more magical and unusual things you feed to it, the stranger it will become.

R: 30' T: objects D: 0

Everything in a 30' cone takes [sum] slashing damage. This spell leaves dozens of deep cuts. It shreds clothing, paper, and other fragile items.

R: touch T: creature D: permanent

Save negates. Save once per mutation. Target gains [dice] random mutations. If the creature chooses to fail its Save, roll double the number of mutations, and the caster chooses which half are gained.

1- MD only return to your pool on a 1-2 for 24 hours 2- Take 1d6 damage 3- Random mutation for 1d6 rounds, then Save with a -4 penalty. Permanent if you fail. 4- Agony for 1d6 rounds. 5- Ravenously hungry. Cannot cast spells until you eat 1 ration. 6- Slough skin. Takes 1d6 rounds to remove. Is disgusting. **Doom of the Biomancer ** 7- Your appearance shifts and randomizes for one day 8- Save at the start of each day or gain a mutation. Save at the end of each day or that mutation becomes permanent. 9- You become a Chaotic Psychoplasm This doom can be avoided by eating the hearts of 100 species, or by falling in love with the same doppleganger three times, or by tattooing rare fixative runes all over your body.
