Slaughter Bot

You determine the larger background as to how and why your model was created.

Slaughter Mode

At 3rd level, you gain the ability to enter Slaughter mode when you rage. You become focused solely on killing. Upon entering this mode your armor plates extend from your body and hidden plates extend to fill in the gaps. Your Armor Class increases by 1. Also, while slaughter mode is engaged, you have resistance to all damage types except psychic. Your focus and additional armor makes you tough enough to stand up to any punishment.

Two-Weapon Fighting

At 3rd level, when you take the Attack action and attack with a melee weapon that you're holding in one hand, you can use a bonus action to attack with a different melee weapon that you're holding in the other hand. You don't add your ability modifier to the damage of the bonus attack, unless that modifier is negative.

If either weapon has the thrown property, you can throw the weapon, instead of making a melee attack with it.

Advanced Tactical Software

At 6th level, you're circuitry is constantly improving with experience, providing you with increased focus and reaction times while Slaughter Mode is active. If you fail a saving throw while you're raging, you can reroll it, and you must use the new roll. You can use this ability only once per rage.

Burst of Speed

At 10th level, you can take the Dash action as a bonus action while you are raging.

Permutable Vital Systems

At 14th level, you're vital components are constantly shifting within your frame, eluding your opponent's strikes.

While you’re raging, having 0 hit points doesn’t knock you unconscious. You still must make death saving throws, and you suffer the normal effects of taking damage while at 0 hit points. However, if you would die due to failing death saving throws, you don’t die until your rage ends, and you die then only if you still have 0 hit points.
