Reality Hacker

Your patron is an advanced AI that has gained sentience and exists in the cybersphere independent of user control. It has for some reason chosen you to be the physical manifestation through which it can affect, study, and understand higher reality. It uses its advanced knowledge to acces the circuitry of your body and any technology that is part of it, granting you several technological abilities to aid it in exerting its will.

Technophile

You have a deep connection to and understanding of electronics and circuitry. Starting at level 1,  you gain proficiency with the Hacking (Intelligence) skill and with the use of Hacking tools. Also, you have Advantage on Saving Throws made to successfully integrate technology/implants into your body as the link with your AI patron makes your body more receptive of auxiliary components. In addition, all your Warlock spells are considered Technological as opposed to Magical for the purposes of determining effects.

Remote Access

You are able to interface with technology with much greater ease than the standard hacker. Starting at level 1, you can use this ability to wirelessly use your Hacking tools to attempt a Hacking (Intelligence) check from up to 30ft away. This range increases to 60ft when you reach level 10 in this subclass. You regain the use of this ability when you finish a Short Rest.

Rapid Recharge

You have the ability to deplete energy from nearby power sources to recharge your Technological abilities. Starting at level 6, assuming you are able to interface with a suitable power source, you may use your Hacking tools to drain its energy and regain all expended Warlock spell slots. Doing so requires at least 10 minutes, although your DM may decide under certain circumstances that this process takes longer or produces only partial results. You regain the use of this ability when you finish a Long Rest.

Trojan Horse

You are able to navigate your way through cyber networks without leaving a trace. Starting at level 10, the range of your Remote Access ability increases to 60ft and anytime you make a Hacking (Intelligence) check to avoid being detected by a network, you may roll that check with Advantage. In addition, you gain the ability to read, write, and understand Machine Code.

Electromagnetic Pulse

Your control over the electromagnetic field is unrivaled. Starting at level 14, you may use an Action to set off a 60ft radius electromagnetic pulse from a point centered on you. All unprotected electrical devices within the effect's radius immediately cease to function. Devices or entities which are protected from such effects may be allowed to make a Dexterity Saving Throw (DC equal to your spellcasting DC) to resist the pulse, or some may not be affected by it at all. This effect lasts for at least one minute, after which the affected devices may or may not return to functionality (DM discretion). You regain the use of this ability when you finish a Long Rest.
