So I'm not taking any damage, and I can't damage mobs either. I've tried disabling each mod individually, and nothing worked. Arrows bounce off me; literally, creeper explosions do nothing.

When I try to kill mobs, I swing but do no damage. I've tried every suggestion I can find, so this is my mod list. Not only this, but mobs deal no damage to me. What could cause this?
