Gadgetsmith

An Artificer (Revised) subclass by KibblesTasty

A Gadgetsmith is
an Artificer whose curiosity and inventive genius have run rampant. While other Artificers may spend their whole career perfecting a single-minded pursuit, a Gadgetsmith believes that quantity is at least as good as quality.

Quick footed and quicker witted, a Gadgetsmith is never caught without another trick up their sleeve. Their minds are always jumping ahead to solve the next problem with a clever gadget.

A Gadgetsmith can come from any walk of life, but usually exemplifies a curiosity and distaste for the suppression of knowledge or technology, usually favoring freedom to experiment, leaning toward more Chaotic behaviors.

Gadgetsmith's Proficiency
When you choose this specialization at 1st level, you gain proficiency with nets, rapiers, whips, and tinker's tools.

Essential Tools
At 1st level, you've mastered the creation of the essential reusable tools for surviving the battlefield as a gadgeteer. You have the following items: {| class="article-table"
 * Grappling Hook. As an attack or as an action, you may target a surface, object or creature within 20 feet. If the target is Small or Smaller, you can make a Strength (Athletics) grappling check to pull it to you and grapple it. Alternatively, if the target is Medium or larger, you can choose to be pulled to it, however, this does not grapple it.
 * Smoke Bomb. As an action, you can use this to cast fog cloud centered on yourself without expending a spell slot. It lasts a number of rounds equal to your intelligence modifier and does not require concentration.
 * Gadgetsmith Weapon. Pick one of Boomerang of Hitting, Impact Gauntlets, Lightning Baton, Repeating Crossbow, or Shock Generator from the upgrade section. You receive this upgrade and it does not count against your upgrade total.

Unlimited Smoke Bombs?
If you or your DM is concerned about the unlimited use of Smoke Bombs, consider adding a Proficiency Modifier number of uses per short rest. This should not mechanically impact their usage, but the reason they do not have the limit is to encourage players to feel free to use them in non-combat situations. With limits, even ones that are not usually hit, players tend to treat their Smoke Bomb as exclusively a combat feature.

Additional Upgrade
At 3rd level, you've mastered the essential tools, and have begun to tinker with ways to expand your arsenal. The number of upgrades you have for your class level is increased by one.

The number of additional upgrades you get increases by one more at 5th level to two more than the class table.

Recycle Gadgets
Starting at 3rd level, during a long rest and taking effect when you complete it, you can disassemble your gadgets and create different ones. When you do this, remove any upgrade you would like, and pick a new upgrade its place.

You still must select upgrades that are valid for the level you gained the upgrade at (e.g. at 9th level, you can only have one upgrade that has a prerequisite of 9th level).
