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!

The following text replaces the text found on pg. 85 of Xanathar's Guide to Everything.

Tinker's Tools include a variety of hand tools, saws, screwdrivers, wrenches, small oil dropper, rubber tubing, and other strange gadgets.

Tinker's Tools weigh 10 lbs and cost 50 gp.

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.

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

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.

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 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.

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.

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. This tool will use miasma as it's base, but your world may feature something else like a runestone with a small reservoir of magic.

This strange, blue-white liquid gas is known as miasma and is produced as a by-product by alchemists and can even be harvested in the Elemental Chaos. Miasma is highly magical and volatile, capable of exploding in a poisonous gas that strangles and suffocates those unlucky enough to be touched by it.

This liquid gas can be bought from a Tinkerer's Guild, alchemist, or other suitable locations for 15 gp for 1 vial. This vial can then be used to provide the necessary magic to power your Magical Objects for a certain amount of time as decided by the object. To remove an old vial from a gadget, you must spend an action to carefully remove it, and then use another action to insert a new vial.

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.

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.

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.

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.

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.

While on, your googles give off a dim green glow for 15 feet from you. If the device suffers a Malfunction while you are wearing it, it short circuits and your eyes are blasted by a bright white light.

Most Mundane objects are very easy to craft and only take a few hours at most. To decide on a DC, the DM should decide how many moving parts or pieces the object is made out of and reference the chart below:

Mechanical objects are more complex than the Mundane and involve some skill to produce them. To decide on a DC, the DM should decide how many moving parts of pieces the object is made out of and reference the chart below:

Most Mechanical objects will rarely be made with magic and instead require the marvels of science and technology.

Magical objects are extremely complex and require a large amount of skill and magic to operate. To decide on a DC, the DM should decide how powerful it is compared to similar spells and reference the chart below:

Most Magical objects require Miasma to power them, and only last for the duration listed per vial. Some magical items are also technological in nature, and can be used with the Technology skill.
