A common yeastomancer, clad in rustic robes woven with strands of wheat, carries a wooden staff adorned with hanging grains. Their eyes glint with the subtle magic of fermentation, and the aroma of freshly baked bread trails wherever they go. In their hands, a small pouch of enchanted yeast, ready to summon doughy allies or unleash the rising power of nature.

The ancient and foreign art of yeastomancy is a taboo offshoot of gastromancy which is the general divination of food. The allure of yeastomancy comes from the many strange abilities it has, such as healing from their delicious bread, altering the environment, poisoning foods, and summoning bread golems; possibly even the dreaded "Breadnaught". Many peoples have tried to emulate the powers of yeastomancy but only the druids have managed to refine it. Clerics and Artificers have tried to summon bread golems but have only managed to make writhing masses of unbaked dough. Yeast is a fickle beast, and only a yeastomancer has the power to tame it.

Yeastomancer's Satchel

2nd Level

An essential part of many casters' equipment is a bag in which to carry the many ingredients and materials they use and yeastomancers are the same. Their satchel comes prepackaged with 10 grams of yeast and flour, as well as a small vial of water. While the user can put other ingredients and items inside the normal-sized satchel, it is not recommended as the satchel is specifically designed to hold yeast and flour. Other ingredients may sully the purity of the flour or yeast.

Minor Gastromancy

Level 2

This feature is a part of any gastromancer's arsenal. Beginning at 2nd level, once per day, regaining uses at dawn, you can touch a material that is no larger than 1 foot in any direction and imbue a taste, smell, look, and/or texture of your choice onto the object for up to 1 hour or until dispelled. These limitations aside from the duration of the spell are null if the item being changed is an edible food. You must rest your hand on the object and say aloud the effects you want to imbue, as soon as you stop, the effects are activated. If you cannot do either of these things before you are done casting the spell, this does not work.

Additionally, you may expend another charge of this spell to make a food item poisoned. This can either be lethal or a mild poison to knock someone unconscious when consumed. Poisoning an item does not change its appearance but it can be detected by someone who can sense magic. The DC for detection is 10+Intelligence+Proficiency.

At level 6, you gain two charges of this spell and at level 10, you gain three charges.

Starch Cloak

3rd Level

Perhaps a rather mundane material to other casters and adventurers, to a yeastomancer it can be the factor between life or a bloody death. You can use this feature as a reaction, thrice per long rest beginning at 3rd level. You can expend one charge of this feature to impose disadvantage on an incoming attack but you have to impose disadvantage before the attack. You can also expend two charges to give yourself partial cover for 1 minute or until dispelled or if you take damage. 

Battle Bread

Level 6

An essential part of any yeastomancer's repertoire is the ability to imbue magical effects into an otherwise mundane piece of bread. The crafting of this divine loaf takes time and materials but is immensely helpful if done correctly and with enough preparation. This feature requires at least 5 grams of yeast and 10 grams of flour - presumably from your yeastomancer travel bag - which the spell does not consume, and at least 1 minute of time. Once crafted, the bread can be eaten as an action and regains 4d4 of the user's health, increasing at 10th and 14th Level. 8d4 and 10d4 respectively.

Additionally, the wielder may choose to add a third ingredient to the bread to affect its properties. These properties depend on the added ingredient. If adding an extremely hot ingredient it might temporarily give resistance to the cold and vice versa, the possibilities are near endless. One might understandably try to add a health potion to the bread to bolster its healing properties. Unfortunately, only the most experienced yeastomancers [Level 18, the health potion's bonus is added to the roll for health] have managed to produce the desired effect. For everyone else, the bread takes on a reddish hue and tastes vaguely sweet but otherwise is the same to the normal effect.

I do not recommend doing this in combat as it takes 10 rounds to fully create.

Manifest Golem

Level 10

One of the most powerful spell or aspect of a yeastomancer's arsenal. Most golems and constructs hail from the Elemental Plains but Bread Golems are a mix of nature and pure magic as the yeastomancer wills it to life. As an action, thrice per day you may either summon 1 True Bread Golem or 1d4+2 Minor Bread Golems, also known as 'Bread Knots' because they have been dulled with garlic. These golems have the same initiatives as the wielder but go after the wielder. Also, the wielder must maintain concentration to keep control of the constructs less they go rogue and are dispelled instantly.

• True Golem. A true golem is a hulking beast of dough that is fairly tough to kill, but where it truly shines is controlling the battlefield. The stats of this beast can be found on the marketplace under True Bread Golem. The Golem is only active for 1 hour before disintegrating and returning to nature or until dispelled or killed. 
• Bread Knot. These very dulled down versions of the bread golem are mainly used as fodder or for suicide missions. The stats of these beasts can be found on the marketplace under Breadknot. These creatures are only active for 1 hour before disintegrating or until dispelled or killed.

Level 18

Manifest Golem is the gateway to the arch ability of the most experienced yeastomancers, temporary summoning of the legendary 'Breadnaught'. By using all three uses of this feature at once, you can have the Breadnaught under your command for 1 minute, until dispelled, or until killed. Your body becomes encased within the Breadnaught and you are essentially Restrained. Only the caster is Restrained, not the Breadnaught itself which is exposed. You keep the same Initiative, and your stats are essentially swapped for the Breadnaught's for as long as you are within the form.

Grand Confluence

Level 14

The Grand Confluence is the penultimate ability for an expert wielder of yeastomancy, providing a magical and immaculate blend of offensive and defensive capabilities in holy culinary excellence. This fusion between magic and food, attack and defense has inspired the name. Once per long rest, as an action you can stir up the very ground of the battlefield and produce but a fragment of the Eternal Loaf. This feature requires only a gram of both yeast and flour, which the spell does not consume, as well as at least 25 gold which the spell consumes.

When activated, creates a colossal loaf of bread anywhere within 30 ft. of the caster that is not already occupied by something. The loaf takes up 5 ft. in length and width but is 10 ft. in height. This bread monument cannot be toppled and can only be destroyed if its health points are reduced to zero, it is dispelled, or after 1 minute. Its health points are 2d10+30, which the caster rolls for. The loaf radiates a 20 ft. aura that grants bonuses strictly to allied persons for as long as they are within the sphere.

Offensive. People gain +10 walking speed and +2 to Hit and Attack rolls. 

Defensive. Upon initially entering the sphere, people gain 2d4+Proficiency mod in temporary Hp. Advantage on all Constitution saves.
