Nanocyte

Your body is infused with nanites programmed to execute specific protocols called arrays. During your daily preparations, you can register one or more pieces of equipment in your possession as nanocyte gear until your next daily preparations. You can’t have more registered nanocyte gear than the number of nanocyte archetype feats you have, and no piece of nanocyte gear can have a Bulk greater than your Constitution modifier.

Your nanites completely cover your registered nanocyte gear, allowing it to be harmlessly broken down and stored within your body. While stowed, your nanocyte gear is hidden from inspection that can’t detect nanites. If your registered nanocyte gear is more than 10 feet away from you at the end of your turn, it turns into its nanite form and returns to your body, stowed. If you are knocked unconscious or die, stowed nanocyte gear appears in your space, fully formed.

In addition, you gain the Gear Array action.

Your nanites shape your body into a fluid weapon with customized features as you require them. When you use this action, you gain a nanite unarmed attack for 1 minute. Your nanite unarmed attack deals 1d6 damage, has the tech trait, and is in the brawling group. When you use this action, choose from bludgeoning, piercing, or slashing, and choose two of the following traits: finesse, forceful, razing, shove, or trip. Your nanite unarmed attack deals that type of damage and has those traits.

Your nanites become a silvery cloud. The cloud covers a number of contiguous 5-foot squares equal to your Constitution modifier, at least one of which must be adjacent to you. It persists for 1 round and grants all creatures within lesser cover.

Your nanites surge out of your body to form a shield. You gain a number of temporary Hit Points equal to your level that last until the start of your next turn.

Your nanites are infused with magic to recreate spell effects. Choose two common cantrips from the arcane spell list. You can cast those cantrips as arcane innate spells at will. A cantrip is heightened to a spell rank equal to half your level rounded up.

Your nanites shoot forth and wrap around the limbs of a creature within 10 feet, binding them together with a powerful magnetic force. The target must attempt a Reflex save against the higher of your class DC or spell DC.

You attack and infect your target, eroding them and hampering their movements from within. Attempt a melee Strike with the required weapon or unarmed attack. If you hit and deal damage, the target takes an additional 1d4 persistent acid damage and becomes clumsy 1 for 1 round. On a critical hit, the target becomes clumsy 2 instead.

You unleash your nanites in a wave of metal. Enemies in a 15-foot cone take 3d6 bludgeoning damage and must attempt a Fortitude save against the higher of your class DC or spell DC. Increase the bludgeoning damage by 1d6 at 8th level and every two levels thereafter.

Your nanites disperse your consciousness and body into a cloud, allowing you to transcend the limits of your physical frame. You gain the effects of a 3rd-rank vapor form spell for 1 minute or until you Dismiss the effect.

Your nanites move as rapidly as your thoughts. You become quickened until the end of your turn and can use the extra action only to use Alteration Array or Gear Array.

Your nanites refract light and reflect sound. If your next action is to use Cloud Array, creatures within the cloud are concealed in addition to gaining lesser cover, and creatures outside the cloud are concealed to those within it.

You've upgraded your nanites to be able to form even more complex weapons. When you use Alteration Array, add the following traits to those you can choose from for your nanite unarmed attack: backswing, grapple, or kickback. In addition, you can choose to give your nanite unarmed attack one of the following traits instead of choosing two from the normal list: boost (1d8), deadly (1d8), or reach.

When faced with danger, your nanites can envelop your body in a shimmering metallic armor. You gain the effects of a 5th-rank elemental form spell, except that you must choose either metal or water as your element, and you gain weakness 10 to electricity while the effect is active. At 14th level, you gain the effects of a 6th-rank elemental form spell, and at 18th level, you gain the effects of a 7th-rank elemental form spell.

Your nanites knit together wounds. You or another creature within 10 feet of you gains fast healing equal to half your level for 1 minute, then becomes temporarily immune to Repair Array for 24 hours. If the creature takes electricity damage, the fast healing ends immediately.

You command your nanites to sweep across the battlefield, damaging your enemies. You extend the duration of the cloud created by your Cloud Array until the end of your next turn, then you can move each square of the cloud up to 10 feet. The squares must each be contiguous to at least one other square of the cloud when the movement is complete. Until the start of your next turn, enemies that start their turn in the cloud take 3d6 acid damage with a basic Fortitude save against the higher of your class DC or spell DC. At 16th level and every four levels thereafter, increase the acid damage by 1d6.

To well-programmed nanites, a body is simply another array to assemble. The triggering creature and its equipment are engulfed in a thick nanite mist and vanish, reappearing in a free space within 30 feet. The target remains at 1 Hit Point, gains a number of temporary Hit Points equal to your level for 1 minute, then becomes wounded 1 or increases the value of its wounded condition by 1.
