A throwing hammer is an off-hand weapon. A character can use a throwing hammer to make attacks even while holding another one-handed weapon in the other hand, and can use the other one-handed weapon to make attacks even if it isn't an off-hand weapon. It is also a heavy thrown weapon, so a character can throw it to make ranged attacks, using Strength instead of Dexterity for ranged basic attacks.
Other classes do not have proficiency with the throwing hammer as a class trait, but any character can become proficient by taking a Weapon Proficiency feat.
Dwarves with the Dwarven Weapon Proficiency racial feature are proficient with the throwing hammer.
