Throughout the history of mortals, war has been a constant. Nations feud over any number of topics, resulting in combat and lives being lost. Rather than work towards a better future, many seek to create perfect soldiers, capable of naturally wielding both spell and sword. Alchemists have tried for centuries to create such a soldier, using various chemicals and surgeries in an attempt to create the ultimate living war machine.

Your powers are a result of such experimentation. Perhaps you were a soldier that signed up for a project you didn't fully understand, or maybe you were bred and grown solely for the purpose of war. You may even be a unique construct, created to surpass the weakness of mortal flesh. Wherever you gain from abilities from, war is in your blood, and adventuring is an excellent way to put your abilities to work.

Combat Installations

Starting at first level, you gain combat abilities from former training or installed memories. You gain proficiency in simple weapons, martial weapons, and shields. In addition, your body has been magically augmented to be more resistant to blows. Your armor class while wearing no armor equals 10 + your Dexterity modifier + your Constitution modifier. You still gain this benefit while wearing a shield.

Alchemic Augmentation

Starting at 1st level, the changes made to your biology begin to manifest in tangible ways. You gain two of the following augmentations of your choice. The augmentations you choose at this level must be different augmentations.

Amphibious Adaptation. You have been augmented with gills and webbed hands and feet. You can breath underwater and gain a swim speed equal to your walking speed.

In addition, whenever you take bludgeoning, slashing, or piercing damage from a creature withing 5 feet of you, that creature takes acid damage equal to your Charisma modifier.

You are proficient with your limb blades. These blades have the light and finesse properties, and deal 1d8 slashing damage on a hit. You can take this augmentation again to make the blades magical for the purpose of overcoming resistance.
