Reinbeast's shield applies after damage. It does sometimes looks like it mitigates some damage but it's just the way HP bar animation works.

Following up on Kalo's response, I BELIEVE that if an ability has a multi hit function, the shield will apply after the first hit, which will then begin to block any subsequent hits. I'm not 100% on this but from what I've seen it appears to function this way.

This Beast is on nerf list for next upcoming upgate!

Is he though? He's been on my top 3 lists of champions to get ever since the first time I ran into him in the arena he had Regen Set on and I had to leave the battle cause it turned into a stalemate and I couldn't kill him. I've loved him ever since. In the back of my mind I always thought he would ge a nerf simply because I only know of 2 champions that are OP right now. And he is one. #DontNerfReignBeast
