Animunculus

Your tinkering has borne you a faithful companion, an Animunculus. It is friendly to you and your companions, and it obeys your commands.

In combat, the defender shares your initiative count, but it takes its turn immediately after yours. It can move and use its reaction on its own, but the only action it takes on its turn is the Dodge action, unless you take a bonus action on your turn to command it to take another action. That action can be one in its stat block or some other action. If you are incapacitated, the defender can take any action of its choice, not just Dodge.

If the mending spell is cast on it, it regains 2d6 hit points. If it has died within the last hour, you can use your smith’s tools as an action to revive it, provided you are within 5 feet of it and you expend a spell slot of 1st level or higher. The Animunculus returns to life after 1 minute with all its hit points restored.

At the end of a long rest, you can create a new Animunculus if you have your smith’s tools with you. If you already have a Animunculus from this feature, the first one immediately perishes. The Animunculus also perishes if you die.

Attachments

You can customize your Animunculus by choosing two of the following attachments (you may not have two of the same attachment). Each attachments adds new actions to your Animunculus. You may swap one or both attachments after your finish a long rest, provided you have smith's tools on hand.

Blade. Unlocks the Blade action. The Blade Attachment counts as a martial melee weapon for infusions and other effects that would alter weapons.

Flamethrower. Unlocks the Flamethrower action.

Lightning Launcher. Unlocks the Lightning Launcher action. The Lightning Launcher Attachment counts as a martial ranged weapon for infusions and other effects that would alter weapons.

Shield. Unlocks the Deflect Attack reaction and gives the Animunculus +2 AC. The Shield Attachment counts as a shield for infusions and other effects that would alter shields.

Rocket Grab. Unlocks the Rocket Grab action. 

Animunculus Extra Attack

Your Animunculus can attack twice, rather than once, whenever it takes the Attack action on its turn. The Rocket Grab and Flamethrower actions count as attacks.

Specialized Mechromancy

You can program your Animunculus with various protocols, giving it special benefits. Only one protocol can be active at a time, and you can change the protocol at then end of a short or long rest, provided you have smith's tools on hand.
