A drakestone golem opens any combat with its petrifying breath, but otherwise relies on its devastating physical attacks to reduce foes to a pulp.
Petrifying Breath (Su): Once every 1d4 rounds, a drakestone golem can exhale a 30-foot cone of petrifying gas (Fortitude DC 27 negates).
Immunity to Magic (Ex): A drakestone golem is immune to all spells, spell-like abilities, and supernatural effects, except as follows. A transmute rock to mud spell slows it (as the slow spell) for 2d6 rounds, with no saving while transmute mud to rock heals all its lost hit points.
