You can create potions from formulas which will have power-like effects when consumed and the ability to create transmutation circles to change materials into others.
You have intuitive knowledge of how to develop new formulas. Natural ingredients as well as brewing equipment are required to create the potions. Consuming too many potions in a short amount of time creates Toxicity and can have adverse health effects on the user. The effect of your potions will fade once it's purged from the drinker's blood. Those potions are limited to powers that can be expressed physically such as regeneration, super strength, enhanced senses, invisibility, etc. At their most powerful they will be as strong as a mid-tier cape.
You have intuitive knowledge of how to create transmutation circles. To perform a transmutation, you need to inscribe the circle on a surface and place the required ingredients inside then touch the circle to activate it. You cannot create materials with power-like properties unless you can study them, this applies to Tinker materials (like alloys). You are not limited in size however the objects must fit within the transmutation circle, at big enough sizes this means taking into account the Earth's curvature. The time to transmute is proportional to the volume.
