So, I actually tested it out with my friend on rumble. He took 3 hand cannon head shots to die regularly, and 5 to get killed with arc blade active. So that's roughly 20% damage resistance. He then took 9 AR headshots to kill me, then 16-17 when I had radiance active. That's not even with radiant skin active. Nearly 50%. And people thing hunters need a nerf? I don't think so
