Siege Walker

A siege walker is a mobile artillery platform, a terrifying threat on the battlefield that carries the burden of immense firepower in a front-line assault.

Massive Firepower

At 3rd level, you gain the ability to wield a weapon with the stabilized quality without the penalties normally associated with failing to properly stabilize such a weapon. While doing so, your movement speed is reduced by half.


At 7th level, when wearing medium or heavy armor, you may use your armor to absorb the shock from incoming bullets. When she is targeted by a ranged weapon attack from a firearm, you may use a reaction to gain resistance to all damage dealt by firearms until the beginning of your next turn.

Once you use this ability, you must take either a short rest or a long rest in order to use it again.

Additional Fighting Style

At 10th level, you can choose a second option from the Fighting Style class feature.

Overwhelming Force

At 15th level, you have learned how to best harness the kinetic force of your enormous projectiles. When you damage a creature with a ranged attack, you may use a reaction to force them to attempt a Strength saving throw. If the creature fails this saving throw, it is immediately knocked prone. The DC for the saving throw is 8 + your Dexterity modifier + your proficiency bonus. You may use this ability a number of times equal to your Dexterity modifier. The usages of this ability reset once you take a long rest.

Unceasing Barrage

At 18th level, you reduce the time required to reload a heavy firearm by one step. Actions become bonus actions, bonus actions become reactions, and reactions require no sort of action to reload.
