Exo-Driver

Your Exo-Diver is an advanced avatar you control that protects you. You start each day with a glowing avatar with Durability (Special temporary hit points) equal to five times your Exo-Driver level + your INT modifier (Minimum 1). The avatar takes the shape of a suit of armor that resembles your ideal armor that glows in with a colored light (Color determined by you). You can suppress the avatar at will making it Invisible though it still feels smooth and cool to the touch.

You regain half your maximum Durability rounded up on a long rest and a quarter Durability rounded up on a short rest. Durability is different from temporary hit points from other features and is tracked separately with temporary hit points being depleted first.

While your avatar is up you have an AC equal to 10 + your INT modifier (Minimum 1) + your DEX modifier (Minimum 1).

When your Durability runs out you are left vulnerable and your adrenaline kicks in. You can make a bonus action attack each turn.

Your aura condenses to an energy blade that extends from your dominant hand (With the statistic of a Shortsword or Rapier) and can be retracted at will (No action required). The energy blade deals Force damage. This state lasts for one minute and cannot be used until you complete a long or short rest.

Your Exo-Driver develops a budding mind of its own. When you fail a saving throw or fail a saving throw that would result in you having a Condition, your Exo-Driver can take the hit for you.
