Homebrew Arc Automaton Species Details

Automatons are mechanical beings built by ancient Dwarven technomancers. 

An automatons appearnce is a direct reflection on the purpose of their creation. Most automatons start off with basic promamming. They start with the ablility to speak and understand Dwarvish. They gain sentience after several centuries of service learning as the go.

Automatons do not need to eat, breath, or sleep. However they do require routine maintenance to maintain functionality. They must spend at least 4 hours in a 24 hour period on preventative maintenance on themselves. Without this their components begin to break down and will cease to function if no maintenance is performed over the course of one year.

As a construct, automatons can be repaired with the mending spell. If the mending spell is cast you, roll one hit die per spell level used and add the results to your hit points. This does not draw from your hit dice pool. Healing spells also work on you as well, following the spell deception for their effects on you.

Ability Score Increases

When determining your character’s ability scores, increase one of those scores by 2 and increase a different score by 1, or increase three different scores by 1. Follow this rule regardless of the method you use to determine the scores, such as rolling or point buy.

The “Quick Build” section for your character’s class offers suggestions on which scores to increase. You’re free to follow those suggestions or to ignore them. Whichever scores you decide to increase, none of the scores can be raised above 20.

Languages

Your character can speak, read, and write Common, Dwarvish, and one other language that you and your DM agree is appropriate for the character. The Players Handbook offers a list of widespread languages to choose from. The DM is free to add or remove languages from that list for a particular campaign.
