# Limbsmith v0.9
#### for [Kibbles' Alternate Artificer](https://www.gmbinder.com/share/-LAEn6ZdC6lYUKhQ67Qk "Artificer")

### Limbsmith
A Limbsmith is an Artificer who has found their own body lacking in some way and began replacing parts of it through artificial ones. Maybe they had a disease they could not recover from normally, lost a limb in a tragic accident and noticed they had a knack for their newfound abilities or simply found themselves wanting physically.

Because of the alien appearance of some Limbsmiths, resembling half humanoid, half construct, they tend to keep their augmentations covered by clothes or robes.

#### Limbsmith's Proficiency
When you choose this specialization at 1st level, you gain proficiency with tinker’s tools and in medicine.
You or anyone else who is proficient with tinker's tools and in medicine can use them to repair you for 10 hit points per hour.
You must at least spend one hour doing this for it to take effect.

#### Augmented Body
At 1st level you have laid the framework for more upgrades to be integrated. You have augmented your body to not only be able to house a subdermal armor, but a plethora of upgrades.

To use these upgrades you have charges at your disposal equal to two times your Artificer level plus half your intelligence modifier rounded down.
Temporary increases like your Hastened Nervous System feature do not increase the number of charges.
Each upgrade description states if there is an active effect that consumes charges and how many.

You replenish half the maximum charges rounded up during a short rest and all of them during a long rest.

<div class='descriptive'>
<section id="limbsmith-augmented-body">
<h5 id="limbsmith-augmented-body">Augmented Body </h5>
Wondrous Item, Medium Armor, Attunement (creator only). 
Armor Class (AC) 14 + Con (max 2)

You are always attuned to your Augmented Body and cannot end this attunement.
You cannot benefit from any armor other than that provided by your Augmented Body.

In each of your arms is a compartment for tool integration. Per default you have tinker's tools and thieves' tools integrated, which do not count towards your starting equipment. You can swap each tool with any other tool weighing no more than 10 lbs and with which you are proficient during a short or long rest.

You have proficiency in intimidation (charisma) checks when your augmentations are visible or the target knows about them. When you are already proficient in intimidation you gain expertise.

#### Integrated Weapons
At 1st level you integrate a melee weapon in each of your lower arms. These weapons cannot have the **heavy** or **two-handed** properties and can be exchanged during a long rest. You are proficient with these weapons and can use your intelligence modifier for attack and damage rolls instead of strength or dexterity. 
You can deploy or retract both or one of them with a bonus action and you cannot be disarmed.
You cannot hold martial weapons in your hands while the Integrated Weapons are deployed.

You can select one non-level-restricted arm upgrade. This upgrade does not count towards the total number of upgrades.

> ### Integrating Magical Items
> Your Integrated Weapons can be exchanged with magic weapons as stated in the Integrated Weapons feature. How they look once they're integrated is up to you. Arguably every weapon has to be customized to fit into your arms, but it is ultimately up to your DM if this should be instantaneous or a downtime activity.
>
>To gain benefits of magical armor (e.g. adamantine or +3 armor) you need to customize and integrate it in a process defined by your DM. This can only be done with medium armor, since heavy armor covers too much of your body to effectively use the features of your Augmented Body. How many of those armor effects can be stacked, should be decided on a case by case basis.
>
>Other magical Items which yield the same effects as upgrades, can be integrated in a conversion process. This counts as if you took the corresponding upgrade, but once integrated you cannot restore the item back to its original form and therefore nobody else can benefit from it anymore.

\pagebreakNum

#### Hastened Nervous System
At 3rd level you can activate an experimental augmentation, that accelerates the flow of time for your nervous system.
This makes you seem faster cognitively than everyone else, which is technically true.

You can increase your intelligence ability score and its maximum by 2 for 1 minute. At 15th level this bonus increases to 4 for 1 minute.
You can do this two times per long rest.

Additionally, you take your studies of anatomy and physiology even further. You gain expertise in medicine.

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

#### Leg-up
At 5th level you can select one non-level-restricted leg upgrade. This upgrade does not count towards the total number of upgrades.

\columnbreak

#### Arcanokinematic Recuperator
At 14th level each time you hit with a melee attack or get hit by a melee or ranged attack you regain 1 charge.

> ### Dispelling and antimagic
> In the course of upgrading your body you will reach a point where some of your vital organs are magical. Being dispelled or inside an antimagic field would therefore kill you in an instant.
>There's two ways you could go about this with your DM:
>
>**Either** you 'never asked for this' and ignore that you're technically half humanoid and half magical item and play as a complete biological organism
>
>**or** you embrace this flaw, which could simply be accepted as is, result in picking only non-vital upgrades and dealing with the resulting impairments or taking the *Weave Lining* upgrade, to tackle at least the life threatening effects of those spells.
>
>Weave Lining provides immunity to the *Dispel Magic* spell to your Augmented Body, upgrades and integrated magical items. Regular magical effects on you can still be dispelled. An antimagic field would leave your body untouched, but keeps you from casting a spell or using an upgrade that generates a spell-like effect protruding from your body.
Your Integrated Weapons and integrated magic armor count as part of your body for this feature but the active effects of skin upgrades form above the lining and can be dispelled.
