I was trying to figure out how this works. From the way I'm understanding is that once I use it I get healed for every weaponskill I use I'd be healed. I've been using it and I haven't been getting that heal everytime I use a weaponskill.

Is there something that I'm missing? I'm not sure if I have to be in the Walking Dead state to be getting that heal as I haven't had the opportunity to take it that far.
