Roboticist

Roboticists make all kinds of robots using their mechanical and arcane knowledge. They build various robots, some combat-focussed, some utility focussed and some both. These robots obey the commands of the roboticist, but some have a bit of sentience and can make decisions on their own.

Robot crafting

At 3rd level when you choose this specialism, you gain the ability to build robots that obey your commands. You become proficient with Tinker's tools and can use them to repair your robots during rests.

- You can create a robot servant, this takes one week of work with 8 hours of work a day, you can work on your robot during a long rest. You can have an amount of robots under your command equal to your proficiency bonus. It takes one spell slot of 1st or higher level per day and 500 GP worth of materials in total.

- If your robot takes damage, you can repair it during a rest, using your Tinker's tools, this takes 1 hour and heals them back to full health. If you know the Mending cantrip you can use this to use your robot to full health too.

- If one of your robots falls to 0 HP they become broken and you can repair it, bringing it back at 1 HP using the Mending cantrip or your Tinker's tools, this takes 3 full combat rounds, this requires concentration.

- If your robot takes more then its maximum HP damage while broken it is destroyed, then you can still salvage some parts if you have access to it. These salvaged parts can be used to build a new robot, reducing the cost of the materials by 100 GP per batch of parts, you can salvage one batch per destroyed robot.

- You can telepathically or verbally give orders to your robots and can choose to give all your robots, one robot, or a specific few robots orders at the same time. Your robots will attempt to obey your commands the best they can and will only listen to you or to people you tell them to listen to. Through your telepathic bond with the robot you can also discern if it is damaged, broken or destroyed. The telepathic bond has no range, but you have to be on the same plane as the robot you want to communicate with for it to work.

- The robot becomes broken if submerged in water and takes 1 point of damage every combat round if in contact with water.

Types of robots
There are a few different types of robots that you can make, all with different functions, some need extra components to be built along with the basic spell slot and materials. All of these robots are immune to the charmed, frightened, blinded, deafened and poisoned conditions and also immune to psychic and poison damage.

Combat bot
This type of robot is trained to use weapons and fight, it is equipped with two one-handed weapons or one two-handed weapon. These weapons can be of any kind; martial, simple, melee, ranged and even special weapons. The robot is proficient with these weapons. To build this robot you need the basic requirements as well as the weapons that it is going to wield.

They are able to climb up or drive up walls and on ceilings, they can move underground and their creator is able to see and use its Tremorsense in a 20 ft. sphere around it, this requires concentration and the robot and the creator have to be on the same plane of existence. The creator cannot see through walls or other solid objects in this way.

Arcane bot
These robots are infused with even more magic then the other robots a roboticist makes and are able to cast spells. An arcane robot can cast all spells that you knew when you created it, these don't have to be artificer spells. Its spell casting modifier and save DC are equal to yours, it casts spells with spell points. The amount of spell points it has is calculated by taking your highest spell slot and the level of that spell slot is how many spell points it has. For example if you are level 10 your highest spell slot is of 3rd level, so your robot has 3 spell points. 1st level spells cost 1 spell point to cast, 2nd level spells two spell points and 3rd level spells three spell points, cantrips cost half a spell point. The robot regains all its spell points during a short or long rest. You can spend one long rest without resting to update your arcane robot so it gains spell points equal to your current highest spell slot instead of the highest spell slot you had when you created it, the spells it can cast then get updated too. In addition to the normal required materials, it also takes an arcane or other magical focus to make an arcane bot, the creator of the robot doesn't need to be able to use this as a focus.

Crafter bot
These robots have proficiency in all Artisan's tools and can make and upgrade other robots if given the order and materials. If a crafter bot makes a robot it is the same as if the creator of the crafter bot had made the robot, when the crafter bot makes a robot it doesn't take the spell slots that are normally required, but it does take the materials. The crafter bot doesn't need Artisan's tools to use them, because they are built into it. To make this bot, you need the normally required materials and any set of Artisan's tools.

Music bot
These robots are able to perfectly reproduce any sound they've heard, as well as play and create songs and other music. They can replicate anyones voice once they've heard the voice and use that voice to say things, even things that they didn't hear that voice say. They can also make multiple sounds at the same time that sound like they come from different things, for example guitar and flute sounds at the same time. They can make up to 5 sounds at the same time. If they've ever taken thunder damage, they can reproduce the sound and deal damage in the same way that the Tunderclap cantrip does. The sounds the bot can make can be any volume, but can't deal damage unless the bot has ever taken thunder damage and the sounds are audible to up to 1 mile at maximum.

Robot upgrades

- At 5th level when you gain this feature, you can upgrade your robots, this takes 100 GP worth of parts, or 1 batch of salvaged parts, upgrading a robot takes 1 short rest where you don't rest. 

- You can now salvage parts from any constructs and not just ones that you've built. You've also become more efficient at making robots and it now only takes 400 GP of materials and 5 days to make one.

Upgrades

Upgrades are applied to a robot to improve them and give them new abilities, or take away weaknesses they have. A robot can have 1 upgrade at level 5 when you obtain this feature, this increases to 2 at level 10, 3 at level 15 and 4 at level 20. Upgrades can be removed once applied but you lose all the parts used to apply it, this can be done during a long rest and doesn't interrupt the rest.

Waterproof
The robot doesn't take any damage from water and has a swim speed of 30 ft., it can also swim completely underwater and function the same way as it would on land.

Database
The robot can speak, write and read any language it has seen before and can perfectly copy written documents and citate things it has heard before, although it doesn't citate in the same voice that it heard the citate in. 

Extra weapon
The robot gains an extra weapon if it is a combat bot, or gains its first weapon if it is a different kind of bot. The weapon can be any weapon, just like the combat bots weapons can be, if this upgrade is applied to a combat bot, the robot is proficient with it. If it is applied to a different kind of robot they aren't proficient with it. This upgrade takes a weapon that the robot will use on top of the normal requirements. It can make attacks with this weapon as a bonus action or simultaneously while attacking with other weapons.

Boost
The robot can move up to triple its speed on one turn, but it needs to wait 1 turn before it can use this again after.

Armoring
The robot gains 2 AC and 3 (1d6) HP

Lights
The robot can shine a light of either a 20 ft. bright light sphere with 10 ft. of dim light around it or a 20 ft. cone of bright light with 15 ft. of dim light around it. It can also flash a very bright light, blinding everything that looks at it for 1d4 turns. It can do all these things and can switch between them at any moment it wants or gets commanded to.

Gasses
The robot can emit a variety of gasses in a 10 ft. sphere around it, affecting everyone inside it, the gasses stay until blown away by a wind of moderate or greater speed or disappear after 2 combat rounds. This ability can be used once per short/long rest, the gasses it can emit are: 
- Smoke, wich heavily obscures vision
- Hallucinogenic gas, wich makes the affected creature frightened of the robot and all the robots allies if the creature fails a Wisdom save with the DC = 8 + robots creators Intelligence modifier.
- Steam, wich deals 2d4 fire damage
- Sleeping gas, wich makes creatures fall Unconscious for 2 rounds if they fail a Constitution save with the DC = 8 + robots creators Intelligence modifier.

Backup battery
If the robot becomes broken it can use this upgrade to instantly get up at 1 HP again, this does not take an action. If the robot is destroyed it can use this to become broken instead. After using this upgrade, it is removed, but it can be added again, with the necessary materials and work.

Robot mixups

- At 9th level, when you obtain this feature, you can add the abilities of a different type of robot to a robot you already have, for example if you have a scout bot you can add the abilities of the stealth bot to it. The robot then has all the abilities, speeds, senses, proficiencies and so on of both robot types and takes the highest ability scores from the two types, for example:
Scout bot ability scores:    Str  12  |  Dex 14  |  Con  12  |  Int  4  |  Wis  6  |  Cha  1
Stealth bot ability scores:  Str  10  |  Dex 16  |  Con  12  |  Int  4  |  Wis  6  |  Cha  1
So a mix of the scout bot and the stealth bot would have the following ability scores:
                                               Str  12  |  Dex 16  |  Con  12  |  Int  4  |  Wis  6  |  Cha  1

- Adding the skills and abilities of a bot type to a bot takes 5 days of work, with 8 hours of work per day and 400 gold worth of materials. If a robot type needs a special material (such as a weapon for the combat bot), you need that as well. Crafter bots can also do this.

Robot improvements

- At 5th level when you gain this feature, you can improve the proficiency bonus or ability score of your robots, you gain 2 upgrade points per robot you have. Once you have spent your upgrade points you can't undo the change that is made. You gain 3 more upgrade points at 10th and 15th level and 4 more per robot at 20th level.

- You can use upgrade points to:
Improve an ability score of a robot by 1
Give a robot + 1 to its proficiency bonus in a skill it is already proficient in
Give a robot 1 extra hit die
Increase a robots AC by 1
Increase any of a robots speeds by 10 ft.

Advanced robot upgrades

- At 15th level, when you gain this feature, you are able to upgrade your robots with stronger and more advanced upgrades. These advanced upgrades take 1 long rest without rest to install and 200 GP worth of materials. A crafter bot can also apply these.

- You can salvage 2 batches of parts from destroyed constructs, you also gain parts when removing normal upgrades from your robots.

Advanced upgrades

Advanced upgrades are stronger upgrades than the normal upgrades you learned to use at 5th level. They don't count towards your normal upgrade count and a robot can only have 1 at a time, this increases to 2 at 20th level. Advanced upgrades can be removed like normal upgrades and you don't get any parts from it.

Sentience
The robot gains sentience, like an awakened creature, but is still obliged to obey you, as long as you treat it friendlily. A sentient robot gains an Intelligence score equal to yours and additionally the robot can choose a class and gain class levels.

Flight
The robot gains the ability to fly and carry creatures while flying. It can only carry objects or creatures of large or smaller sizes while flying, the flight speed it gains is 60 ft. (Hover), but this is reduced to 40 ft. (Hover)  when carrying something. If it has the "Boost" upgrade it can use this while flying too.

Pocket dimension
The robot can make a portal to a pocket dimension, the protal can be any size smaller then 15 x 15 ft., in this pocket dimension there is nothing except ground, wich can be any sort of ground type that the creator of the robot wants (dirt, sand, etc.). The dimension seemingly goes on forever, but you can only move around and store things in a space of 60 x 60 x 20 ft., after wich there is a forcefield that can't be dismissed in any way. Anything that can fit through the portal can go to the dimension and living creatures can live there as long as they have food and water. Any living creatures inside can only leave with permission of the creator of the robot or with a spell that allows them to travel inbetween planes of existence.

Teleport
The robot can teleport to its creator and vice versa, it can also teleport to other robots that are made by the same creator. This only works if the robot/person teleporting is on the same plane of existence as the robot/person it is teleporting to. The robot/person that is teleporting gets teleported along with everything they are holding onto, wearing and carrying. This upgrade also allows the creator of the robot to swap places with it.
