Was doing some testing with a Chimera character, and realized that while mixed martial arts does correctly work in terms of allowing a sub-weapon grudge claws, it doesn't seem to like it when you use a fist (in my case, Hands of the Giant) in the main hand slot along with ambidextry. Even with the skill toggled on, you will always use the main-hand fist weapon instead of the bare fist weapon.

For further clarification, I do have grudge claws as a sub attack, and meet the conditions for mixed martial arts. It's just the ambidextry toggle that won't allow for its usage on any skill.

This isn't really a bug, it's more of how the skill functions. It will only try to use Bare Fists if there isn't another valid item equipped, so if you have a Fist equipped and you use a Fist skill, it will always use it.
