Disciple of the Eban and Verdant
Once every few hundred years to a millennium a rare situation occurs. An orphan is found by a Black dragon and a Green dragon that agree to train the orphan to topple an empire or power that threatens them. Their skills become unrivaled as they learn skills from their draconic masters. They are single minded and determined as they seek to avenge their masters or fulfill their orders.
Subclass Features
Trainings of the Amphibious Predators
You have a Swimming speed equal to your movement speed. You attack normally while in water unless the attack is ranged and you swim silently.
If the first attack you make during combat is coming out of water, the attack becomes a critical hit as you capitalize on the surprise. If you attack this way you can Disengage without taking an action as long as you move back into water.
Boons of the Black and Green
You are blessed by your draconic masters and gain the following features
You have Resistance to Acid and Poison damage and Immunity to the Poisoned condition.
You have Blindsight for 10 ft.
You can breathe air and water.
Caustic Sneak Attacks
You can magically change the damage of your Sneak Attack bonus damage to those of your draconic masters. You can choose your Sneak Attack damage to be dealt as Acid or Poison damage.
If you choose to use the Cunning Strike Poison option you deal Poison damage equal to your Rogue level on a failed save.
If you choose to use the Cunning Strike Trip option you leave corrosive Acid on them that lowers their AC by your DEX modifier (Minimum 1) until the end of their next turn, even if they succeed in remaining upright.
Frightful Presence
You unleash a fraction of your master’s signature ability. As an action each creature of your choice that is within 120 ft of you and aware of you must succeed on a DC 8 + your CHA modifier + your Proficiency Bonus WIS saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is Immune to your Frightful Presence for the next 24 hours.
Transformation of the Eban and Verdant
You take on a transformation brought upon your draconic blessings that has lain dormant within you giving you the following features for one minute as an action once per long rest.
You gain a Flying speed equal to your movement speed as twin green and black wings sprout from your back.
Scales grow on your exposed points giving you +2 AC.
You are Immune to Acid and Poison damage.
Torrent of Acid and Poison
You can unleash a torrent of your master’s combined elements. You exhale an Acidic and Poisonous torrent in a 90-foot cone as an action. Each creature in that area must make a DC 8 + your CHA modifier + your Proficiency Bonus CON saving throw, taking 4D6 Acid and 4D6 Poison damage on a failed save, or half as much damage on a successful one.
You can use this feature once per long rest.
