i have invented a truly rough test of skill for the arenas,NEAR DEATH RUN! first,you must let the boss damage you untill you are one hit away from death,and then you go through the rest of the arena or true arena like that! i know it sounds tough,heck, i cant even beat it! but i have seen some extremely talented players on miiverse,so im sure someone can do it. if you do try this,good luck!
