Fabrication

Fabrication
Sometimes you don't have exactly what you need, and that sucks. You could scavenge or raid and hope you get what you want, but that leaves a lot to chance. If you have the correct tools and enough raw materials, you could instead try to make whatever it is that you want.

Step 1: Assemble Workstation
In order to make something, you'll need tools. For some simple objects, such as a sling bullet or a pointy stick, you won't need elaborate or specialized tools, though the work will be impeded. Working with no tools or improvised tools will confer disadvantage. If you want to make a Healing Potion or a Longsword, you'll want the best tools you can get. A simple tool is enough to get the job done and are easily fabricated, but a full workstation is an invaluable asset in fabrication but difficult to transport and assemble. Working with a specialized workstation will confer advantage.

Step 2: Gather Resources
You'll need a variable amount of components that are usually specific to the thing you wish to make in order to make it. High quality resources will reduce the DC of the creation, whereas low-quality resources might make the item itself less effective. For example, a common healing potion might require Peacebloom, water, and an empty bottle. If you provide flowers you've grown yourself with quality fertilizer, the DC to create it might reduce by 5. However, if you use wild peacebloom you found last week the amount of HP restored might be reduced to 1d6+1.

Step 3: Create the Item
Once you've got your materials and tools, simply roll a final crafting check. If you meet the DC of the item, it is successfully made. If you fail by 5 or less, time is wasted and the item is not made. If you fail by 5 or more, the item is not made and all resources are destroyed.

Extras

 * Once you've made an item at least 3 times or have a detailed recipe, you may choose to have the result of the dice roll to be a 10. This phenomena is known as "Mastery."
 * An ally helping you grants you advantage on the roll. If you have "Mastery" with an item, an ally instead grants you a +5 bonus on the check.
