Alea Publishing Group has released Golem Grimoire.
From their announcement:
Do you desire to forge a golem, a mighty instrument of destruction and servitude? Have your ever wished to armor yourself within the hulk of such an awesome construct, to have your enemies crumble before you beneath a powerful slam, a rampaging brute, or the fumes of noxious gas? Look no further - the Golem Grimoire is here.
It offers four new golems, skill challenges, the golem grimoire magic item, and new masterwork golem armors to entomb yourself in walking hulk.
