At 17th level, a Foehammer gets the ability to treat feats applying to specific weapons in the hammer group to all weapons in that group. Will this allow Weapon Focus/Specialization feats to stack? For example, one chain set focused on the Warhammer, the other focused on the Light Hammer.
Also, does the Hammer to the Ground ability provoke an AOO without Improved Trip?
Thank you!
I'd say "yes" to the first, and "no" to the second.
