Animgraph Set Variables in Character

I control an equip state via a variable in the character, however I would need to reset the variable from the animgraph, can I run the cast to XuFuCharacter node, if so how?

I have it working using a montage and running through the eventgraph but wondered if it could be done through state and the animgraph?

No. You have to use Anim Notifies for this.
