Tinker's Tools

Your set of tools may be dirty and grimy, your blueprints smudged up, but that's never stopped you from creating wonderful and magnificent creations!

Crafting

To craft an object, you must have proficiency in the use of tinker's tools and you must know the object you wish to craft. After choosing the item to craft, you then must gather the required ingredients and then begin crafting the item.

You can craft three different types of objects: Mundane, Mechanical, and Magical. Generally, the more complex an item is, the more likely it is going to be magical. Crafted items, once created, last until they are broken and any item that is more complex than Mundane requires a blueprint to build.

Using Your Tools

When you wish to construct an object, you must first have blueprints to work from, unless you are attempting to make a Mundane object.

Blueprints
To create blueprints, you must spend 8 hours working on your blueprints and then make an Intelligence (Tinker's Tools) check. The DC is determined by the type of object you are attempting to create and it's complexity. When you are creating your blueprints, there are no gold costs for this day. On a failed check, you make no progress for this day and must spend another day creating a set of blueprints.

Crafting the Object
Once you have your blueprints, you can begin assembling your object. You must gather the raw materials and then spend several hours crafting the item. The raw materials are abstracted out into a gold cost for the object, and you must spend that amount of gold for every 8 hours of work on the object. Once you finish 8 hours of work on the object, you must attempt a Dexterity (Tinker's Tools) check to make progress on your object.

On a failed check, the gold cost for the past 8 hours is expended but you make no progress on your object. You must pay the gold cost again and re-attempt the check after 8 hours.

The DC for crafting an object is based on the object you are attempting to create and it's complexity.

Mundane Objects

Mundane objects are simple items that don't require much work to produce. They often feature very few moving parts and very simple in their construction. These items don't require a blueprint to produce them, only time and a few raw materials.

Mechanical Objects

For more complex and mechanical pieces, Mechanical objects use a tiny bit of magic but largely rely on your engineering abilities and skill. These objects are often seen as marvels of magic by the general population, even if they use no magic in them. These items require a blueprint to produce them due to their complexity.

Magical Objects

For some of the most complicated objects, magical objects are a blend of magic and technology that must be powered and can only work if magic is placed in them. While a tinkerer doesn't have to be proficient in magic to craft such an item, they need something magical to power the item. This could be miasma, residue from a slain elemental, or something else that contains magic in its essence.

Using your Objects

With your tools, you can create problem-solving objects to help you on your adventures, or just make life easier. These objects are largely restricted to solving problems in the world, not necessarily for harming your opponents. These objects can be as complicated as a breathing apparatus to allow you to breathe underwater to a bag of ball bearings to trip up your foes.

Malfunctions & Magical Objects

After each use, a Magical object has been put under strain and may suffer from a Malfunction or even a Catastrophic Failure. To determine what strain your object has gone through, after each use of the object and no matter how long, you must roll a Dexterity (Tinker's Check) against the Malfunction DC of the object.

On a failed check, the object suffers a Malfunction and the object is not usable until you take a short rest to repair it (no check required). If you fail the check by 5 or more, your object suffers a Catastrophic Failure and is broken. To repair your object, you must spend half the time required to build the object, this requires you to pay the gold cost if it will take more than 8 hours to repair the object.

Workshops

Some objects you might wish to create might make travel with them impossible. The DM may decide that some objects are too large or heavy to carry around, forcing you to use a workshop to work on the object.

Complexity

The complexity of an object is based on its designation; Mundane, Mechanical, and Magical.
- Mundane objects are the easiest to create and have the lowest DC, as well as require the least amount of time to craft. These objects can't malfunction.
- Mechanical objects require some engineering skill and have higher DCs.
- Magical objects are complex and require a power source to charge them. They are prone to malfunctioning and breaking down.

Mundane Objects

Abacus

A standard tool used to make calculations.
Complexity Mundane
Crafting Time 1 hour
Cost 1 gp
Materials Needed Any
Craft DC 8

Backpack

A backpack is a leather pack carried on the back, typically with straps to secure it. A backpack can hold 1 cubic foot / 30 pounds of gear.
Complexity Mundane
Crafting Time 1 hour
Cost 1 gp
Materials Needed Cloth, Leather
Craft DC 5

Ball Bearings (Bag of 1,000)

As an action, you can spill these tiny metal balls from their pouch to cover a level, square area that is 10 feet on a side. A creature moving across the covered area must succeed on a DC 10 Dexterity saving throw or fall prone. A creature moving through the area at half speed doesn't need to make the save.
Complexity Mundane
Crafting Time 8 hours
Cost 5 sp
Materials Needed Metal
Craft DC 8

Book

A book might contain poetry, historical accounts, information pertaining to a particular field of lore, diagrams and notes on gnomish contraptions, or just about anything else that can be represented using text or pictures. A book of spells is a spellbook.
Complexity Mundane
Crafting Time 8 hours
Cost 12 gp 5 sp

Grappling Hook

When tied to the end of a rope, a grappling hook can secure the rope to a battlement, window ledge, tree limb, or other protrusion.

Alarm Clock

This hourglass is attached to a set of weights that produces a great noise when the sand runs out after a certain amount of time. Any creature asleep within 15 feet of the alarm clock awakens when the time runs out. As an action, you can set the time to up to 8 hours.

A dagger is incorporated into a device operated by a wrist. As an object interaction, a creature can flick their wrist and a dagger appears. This device is large enough to carry a dagger or other small objects per the DM's discretion.

Windup Toy

This small windup toy bears a vague resemblance to a duck. As an action, you can wind up this toy and release it on the ground. Roll initiative for this toy, and on its turn will walk up to 30 feet in a straight line. On its next turn, it produces a huge amount of noise, like that of cymbals crashing together. It produces this noise a number of rounds equal to the number of feet it walked, divided by 5.
