Battle Engineer

The battle engineer focuses on direct combat with weapons and magical rune arms. They often use heavy or light repeating crossbows to deal heavy damage at long range, and have one-handed weapons to participate in melee combat. They also use rune arms to augment their damage, taking advantage of the built-in cannon.

 

 

Runic Arm

Starting at 3rd level, you craft your most powerful tool, a rune infused arm. This arm replaces your or someone else’s natural one, works as a suit of armor, or covers your arm. Regardless, it has the following properties:

• You can use your Intelligence, instead of Dexterity or Strength, for attacks and damage rolls with weapons wielded in this arm.
• You count as one size larger when determining the carrying capacity.
• You gain proficiency with martial weapons.

Battle Runes

At 3rd level, you learn how to infuse the runic arm with different runes, for distinct situations. You can change the active rune whenever you finish a short or a long rest:

Runic Canon

At 5th level, you craft the most powerful weapon in the arm, the runic cannon. As an action on your turn, you can condense the power of the runes into sheer arcane might.

Make a ranged spell attack against a creature within 90 feet, causing 4d8 force damage on a hit. This damage increases in 1d8 at 11th (5d8) and 17th level (6d8).

After using your Runic Cannon, you can make a single weapon attack as a bonus action. Your Runic Cannon drains the energy of the runes, and you can't use them until the start of your next turn.

 

 

Rune Activation

Starting at 9th level, you can activate special powers contained inside your runes. Once you have activated your rune, you can't activate that same rune again until you finish a long rest.

Rune Mastery

At 15th level, you finally master your arm's rune, unlocking their full potential.
