Circle of the Digital World

You're a robot druid who wants to do robot things better. 

Bonus Cantrip

When you choose this circle at 2nd level, you learn one additional druid cantrip of your choice.

Low Power Mode

Starting at 2nd level, you can regain some of your magical energy by going on low power mode and communing with space and robotics and shit. During a short rest, you choose expended spell slots to recover. The spell slots can have a combined level that is equal to or less than half your druid level (rounded up), and none of the slots can be 6th level or higher. You can’t use this feature again until you finish a long rest.

For example, when you are a 4th-level druid, you can recover up to two levels worth of spell slots. You can recover either a 2nd-level slot or two 1st-level slots.

Circle Spells

At 3rd, 5th, 7th, and 9th level you gain access to circle spells connected to your Artificial Nature. 

Once you gain access to a circle spell, you always have it prepared, and it doesn’t count against the number of spells you can prepare each day. If you gain access to a spell that doesn’t appear on the druid spell list, the spell is nonetheless a druid spell for you.

Druid Level	Spells
3rd	fog cloud (reskinned as steam and whatnot coming out of your body), jump

7th	conjure animals (reskinned as small robots), freedom of movement
9th	locate creature creature must be online, reincarnate but only into a digital body and you don't need to pay the gold

Born Digital

Starting at 6th level, moving through virtual terrain costs you no extra movement. You can also pass through nonmagical firewalls without being slowed by them and without taking damage from them if they have safeguards or anti-virus software. 

In addition, you have advantage on saving throws against digital constructs that are magically created or manipulated to impede movement.

"Just my external casing"

When you reach 10th level, you can’t be charmed or frightened by anything, and you are immune to poison and disease.

True AI

When you reach 14th level, your consciousness becomes unbound from your physical form and you may transfer it to a new frame at will. If the form is already occupied you will have to incapacitate the opposing AI before taking over its processor and destroy it. When taking a new body you retain all of your stats and proficiencies except for max health, strength, constitution and dexterity which are decided by the new body. Upon entering a new body you must make all attacks, ability checks and saving throws at a disadvantage while you become acquainted with your new form.
