Restriction:  Warforged or other similarly mechanical race

 

You never need to sleep; you never need to eat; you never need to stop.  And now, you never need to reload.

Reploids are the next evolution in combat.  Utilizing the never resting, never ceasing bodies of mechanical beings, we now have a soldier who is always armed, always ready for the fight.

Integrated Arm-Cannon

At 3rd Level, you have modified your mechanical body to have an integrated Cannon.  Your arm itself is a weapon in the form of a powerful magical cannon that fires blasts of charged energy. At will you can switch your hand and arm into the Arm-Cannon or back again.  While in hand form, it takes a DC20 Perception check to notice the 'irregularities' in your arm.

You are proficient with the Arm-Cannon. The Cannon is a two-handed ranged weapon that deals force damage based as shown in the Arm-Cannon column of the Arm-Cannon Damage table. Its normal range is 60 feet, and its maximum range is 300 feet. The Arm-Cannon uses Dexterity for its attack modifier and Intelligence for its damage modifier. This weapon does not require ammunition, as it fires a blast of energy generated from your own body.

In addition to its base damage, you can Charge your arm-cannon to deal additional damage.  As a Bonus action, you can pool energy into your arm, increasing the damage of your next attack by 1d6.  This damage increases as the base damage of your arm-cannon increases.  You can hold a maximum of 2 charges in your arm at any time, but holding a charge will require a Concentration check if you are attacked.

 

Level	Arm-Cannon Damage
3rd	1d6 + Int
7th	1d8 + Int
10th	1d10 + Int
15th	1d12 + Int
18th	2d6 + Int

At 3rd level, you gain the ability to cast spells by channeling the energy within you.  Your spell casting ability uses the the below table, and your spells known list uses the Spells Listing for the wizard spell list.  Your spell focus is your Arm-Cannon, and you can replace the material components(up to 50 gp) for spells with your internal energy.

Improved Arm-Cannon

At 7th Level, your expertise with your own body has allowed you to make upgrades to your Arm-Cannon.  You can implant up to 3 different Gemstones of at-least 500gp.  Each gemstone will allow you to change the damage type, depending on the table below.

Gemstone	Damage Type
Ruby	Fire
Sapphire	Cold
Amethyst	Lightning
Emerald	Acid

Improved Capacitors

At 11th Level, the maximum number of charges your Arm Cannon may hold is increased by 1.

Nova Strike

At 15th level, as a Reaction to being attacked in melee, you can overload your Arm-Cannon.  The force of discharge causes you to deal 2d10 Fire and 2d10 Force damage to any creature within 5 feet of you, and forces you in a direction of your choosing up to 15 feet away.  This forced movement can not provoke an Attack of Opportunity.

Reploid Overload

At 18th level, you unlock the full power of your enhanced frame. As a standard action, you can over-charge your whole body.  For the next minute, you gain the following abilities:

• Your base movement speed is doubled
• Your base Arm-Cannon damage is doubled
• You are surrounded by excess energy, increasing your AC by 5

At any time during this period, you can shunt all of the excess power in your system to your Arm-Cannon.  As a standard action, you may fire a huge blast of energy in a 15ft x 120ft line. All creatures in this line must make Dexterity saves; failure means they take 5d10 Radiant and 5d10 Force damage, while success means they take half.  Completing action will deactivate the above temporary abilities.
