It seems that as my health bar goes down the hits by mobs go up. It doesn't seem that the hits are stronger or lighter just more frequent and it happens often enough that it doesn't seem random. Also one other question how is ones health regenerated ? At one time I read that is was by a percent of ones health and then later on I read that it was a set amount regardless your total health points. I read both post a long time ago so I am wondering if the regeneration has changed again.
