Class Features

As a Tinker, you gain the following class features when you reach the specified levels in this class. These features are listed on The Tinker table.

Cobble

Starting at 1st level, your skill as a tinker helps you to make quick repairs and even improvements while on the road. You know the mending cantrip, and can use your tinker's tools as a spellcasting focus for it.

Additionally, your quick thinking and innovative spirit allows you to quickly cobble together a solution to any problem you face, represented by your Cobble die, which is a d4.

Using Cobble Die. You can use your Cobble die in the following ways:

• When a creature within 30 feet of you that you can see makes an attack roll, you can use your reaction to roll your Cobble die and add the number rolled to the attack roll.
• When an attack roll is made against a creature within 30 feet of you that you can see, you can use your reaction to roll your Cobble die and add half the number rolled to the creature's AC until the start of its next turn.
• When a creature within 30 feet of you makes an ability check, you can use your reaction to roll your Cobble die and add the number rolled to the ability check.

Number of Uses. A Cobble die is expended when it is rolled. You can use a Cobble die a number of times equal to your Proficiency Bonus. You regain any expended uses when you finish a long rest.

At Higher Levels. Your Cobble die changes when you reach certain levels in this Class, as shown in the Cobble Die column of The Tinker table. The die becomes a d6 at 5th level, a d8 at 9th level, a d10 at 13th level, and a d12 at 17th level.

Gadgetry

Also at 1st level, you have devised Schematics, ingenious or novel designs for contraptions with a range of effects.

Tinker Specialization

At 2nd level, you specialize in a specific kind of tinkering. Your choice grants you features at 1st level and again at 6th, 10th, and 14th level.

Engineering Style

Beginning at 3rd level, you have developed a style of tinkering, that roughly aligns with the design philosophies of a certain race known for their innovation. Choosing between the following Engineering Styles, you learn new ways to use your Cobble die.

Draenei Engineering. Immediately after a creature within 30 feet of you that you can see takes damage, you can use your reaction to roll your Cobble die and restore a number of hit points equal to the number rolled.

Dwarven Engineering. When you use your Cobble die to increase a creature's AC, the creature gains temporary hit points equal to the number rolled on the Cobble die.

Forsaken Engineering. When a creature within 30 feet of you that can see forces another creature to make a saving throw, you can use your reaction to roll your Cobble die and add half the number rolled to the saving throw DC.

Gnomish Engineering. When you use your Cobble die to increase a creature's ability check, you can roll the Cobble die again and choose which roll to use.

Goblin Engineering. When you use your Cobble die to increase a creature's attack roll against a target, the target and each creature of your choice that you can see within 5 feet of it must succeed on a Dexterity saving throw against your spell save DC or take fire damage equal to the number rolled on the Cobble die.

Sin'dorei Engineering. When a creature within 30 feet of you that you can seee is forced to make a saving throw against a spell, you can use your reaction to roll your Cobble die and add the number rolled to the saving throw.

The Right Tool for the Job

Also at 3rd level, you've learned how to produce exactly the tool you need: with artisan's tools in hand, you can create one set of artisan's tools in an unoccupied space within 5 feet of you. This creation requires 1 hour of uninterrupted work, which can coincide with a short or long rest. The tools are nonmagical, and they are disassembled when you use this feature again.

Ability Score Improvement

When you reach 4th level, and again at 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.

Extra Attack

Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.

Tool Expertise

At 6th level, your proficiency bonus is now doubled for any ability check you make that uses your proficiency with a tool.

Scavenger

Starting at 7th level, you regain all your expended uses of Cobble when you finish a short or long rest.

Improved Cobble

When you reach 9th level, you achieve an advanced understanding of slapdash engineering. Your Cobble die can be used on creatures within 60 feet. Additionally, you gain additional ways to use your Cobble feature:

• You can touch a gadget or magical item with a limited number of uses and expend a Cobble die to restore one use.
• You can touch a gadget or magical item with a limited number of charges and roll a Cobble die to restore a number of charges equal to half the number rolled.
• You can touch a vehicle or object with hit points and roll a Cobble die to add double the number rolled as temporary hit points for the object.

Arcane Understanding

At 15th level, your discoveries in the field of magical science allow you to attune with up to 4 magical items at once.

Additonally, you ignore all class, race, spell and level requirements on attuning to or using a magic item.

Improvisation

At 17th level, when you roll initiative and have no uses of Cobble left, you regain one use.

Additionally, as an action, you can choose one of the schematics you know and replace it with another schematic that you could learn at that level.

You can use this feature twice, and regain expended uses when you finish a long rest.

Magnum Opus

At 20th level, you have achieved a mastery of tinkering, and can devise a marvel of engineering; your masterpiece.

Creating your masterpiece may take weeks, months, or even years depending on the scope of the project. Work with your DM to figure out the logistics of gold cost and time spent. Examples of masterpieces may be High Tinker Mekkatorque's efficient Deeprun Tram, Orgrimmar's design by Chief Engineer (and future Trade Prince) Gazlowe, or Grand Apothecary Putress' devastating Blight.

Alchemical Mastermind

Sapper Specialization

Artillerists, sappers, demolitionists, grenadiers, all similar names to describe the same thing: experts in the handling of explosive weapons. The mischievous goblin sappers are known throughout the Horde for their incredible aptitude for destruction, and dwarven mortar teams proved invaluable to the Alliance in every battle they've appeared.

Sappers are masters of one thing, explosions! They use this specialty to carve ruin into enemy ranks and level fortifications.

Explosives For Dummies

When you choose this specialization at 1st level, your affinity for destruction results in your discovery of explosive munitions. Whenever you finish a long rest, you can produce a number of explosive munitions equal to your Proficiency Bonus. When you do this, you choose between creating an Impact Grenade or Pressure Mine, with the effects for each listed below.

• Impact Grenades. As a bonus action, you can throw a grenade (to a point within 30 feet) or hurl it with a sling (to a point within the sling's long range). It detonates on impact, and each creature within a 10-foot radius must make a Dexterity saving throw against your Gadgetry save DC. On a failed save, affected creatures take 2d6 fire damage on a failed save and are pushed 10 feet from the center of the explosion. Creatures that succeed take half as much damage and aren't pushed.
• Pressure Mine. As a bonus action, you can set up a mine to cover a level, square area that is 10 feet on a side. There must not be a creature within the targeted area when you set up the mine. When a creature moves across the covered area, the mine detonates forcing all creatures within 5 feet of the covered area to make a Dexterity saving throw against your Gadgetry save DC. On a failed save, affected creatures take 2d8 fire damage and are knocked prone. Creatures that succeed take half as much damage and aren't knocked prone.

Creating an explosive munition in this way requires you to have tinker's tools or gunsmith's tools on your person, and any explosive munition you create with this feature lasts until it explodes or until the end of your next long rest.

When you reach certain levels in this class, your explosive munitions' damage increases by one dice when you reach 6th level (3d6 and 3d8, repsectively), 10th level (4d6 and 4d8), and 14th level (5d6 and 5d8). Each explosive munition you produce can be of a different type.

Battlefield Demolition

At 6th level, you are a scholar in explosive theory. Your bombs deal twice as much damage to objects and structures and you have resistance to damage dealt by your own bombs.

In addition, you can put together improvised explosives quickly. As an action, you can expend a Cobble die to produce an explosive munition, as detailed in your Explosives For Dummies feature.

Doctorate In Destruction

Starting at 10th level, you've mastered the perfect time it takes to prime an explosive. As an action, you can cause your next explosive munition to explode unexpectedly, giving all affected creatures disadvantage on their saving throw. You can use this action only if you haven't moved during this turn, and after you use the action, your speed is 0 until the end of the current turn.

You can use this feature twice, and recover expended uses at the end of a long rest.

Master Blaster

At 14th level, you have achieved a mastery of the explosive arts. Magical barriers that can be destroyed by the Disintegrate spell (like Wall of Force, Otiluke Resilient Sphere, etc.) are also destroyed when they should take damage from one of your explosive munitions.

Additionally, When one of your explosive munitions are triggered, you can choose it to be The Big One, causing it to deal an extra 5d6 thunder damage. Once you use either feature, you can't use it again until you finish a long rest.

Gadgeteer Specialization

Gadgeteers are tinkers that combine the benefits from both magic and technology to create wondrous magical devices. Most gadgeteers are gnomes, blood elves, and draeneis, with gnomish gadgeteers establishing the Enlightened Assembly of Arcanology, Alchemy and Engineering Sciences.

Prepared with all forms of gadgets and devices to help in any situation, the gadgeteer is often seen as the quintessentiai tinker.

Steam Warrior Specialization
