MH3U In-depth: Armor(Part 1) Armor is a very important part of the game and hunters need it to survive all fights. The natural defense the game gives you is 50 points, which basically mean that you won't die in one hit by a mere Aptonoth. This clearly isn't high enough to fight any large monsters, such as a Rathian or Barroth, so that's where armor comes in.
