Alloyed (Ex)

A cannon golem’s slam and cannon attacks count as adamantine, cold iron, and silver for the purpose of overcoming damage reduction.

Blasting Critical (Ex)

When a cannon golem confirms a critical hit with a slam attack, it can make one cannon attack against that target as a free action (as long as the cannon is loaded).

Cannon (Ex)

The golem’s cannon has a range increment of 100 feet and deals 6d6 points of bludgeoning and piercing damage on a hit with a x4 critical modifier. The cannon’s magazine can hold up to 20 cannonballs at a time—reloading a single cannonball into this magazine is a standard action for the golem, while loading a cannonball into the cannon itself to fire it is a swift action; this allows the golem to take two shots per round with the cannon.

Gun Training (Ex)

A cannon golem adds its Dex modifier to the damage dealt by its cannon.

Immunity to Magic (Ex)

A cannon golem is immune to spells and spell-like abilities that allow spell resistance. Certain spells and effects function differently against it, as noted below.

  • Any spell with the water descriptor that affects a cannon golem renders its cannon unusable for 1 round (no save).
  • A heat metal spell causes the golem’s cannon to instantly backfire, dealing 6d6 points of damage to the golem and staggering it for 1 round (no save).


A cannon golem is built from 2,000 pounds of adamantine, brass, cold iron, and mithral.
