Block

Over the next week, Max regularly broke both his arms while training the 'Block' move. 

The training was so intense that he actually got strength, constitution and endurance stat point bonuses from keeping at it daily, but the truly difficult aspect of the training was the willpower. 

Everytime that Max faced the incoming boulder knowing full well he did not have the necessary strength or skill to stop it, he had to steel his mind to stop the boulder with all that he got. 

Everyday Max would break his arm bones and everyday Rhea would heal him up, as even while sleeping he started to dream about the boulder and how badly he wanted to stop it.

After 14 days, Max's palm prints were visible on the large rock as it became abundantly clear as to how Max was approaching the problem.
