So limit it to Rage-only and remove the reach, and all you get is a trigger for 1 weapon mastery ability? Doesn't feel right for level 10 ability to me.I'd be happy enough with:
While your Rage is active, you channel the grasping branches of the World Tree. When you hit why a Melee attack, you can activate the Push or Topple property, even if you are using another Mastery property with that weapon.
Just subtract the range boost/vines thing, and forgive any templating mistakes on my part.
I really like the extended reach (with a reach weapon, the reach is 20ft., which is unique). It feels like a Warden of the World Tree, channeling its might like the reaching branches and roots. I'm actually a really big fan.
