Prerequisites

Becoming a MWW is ridiculously hard. You must meet the following criteria:

Olympic. You must have a Strength score of at least 17 and a Constitution score of at least 15. Massive weapons require the might to carry them and the stamina to wield them.

Additional Attack. You must have a feature that allows you to attack an additional time (such as the Extra Attack feature) independent of any non-action resource.

Possession of a Massive Weapon. Whether you found or forged yourself a massive weapon, you must have one to wield in order to take levels in this prestige class. This weapon can either be a sword, an axe, a maul, a lance, or a polearm; or some object that resembles one of those five (such as a ship's anchor resembling an axe, or the mast resembling a polearm).



Once you meet these requirements, you can take a level in this class upon your next level up.
