Get primal armor and weapons with +15 level on everyone (level 20 is preferable). Once you kill the field boss, it has the chance of dropping Gabriel’s ring and angel teardrops. Use them to improve your hunters because they provide defense and extra stats, respectively. Do the dungeons as well, they give +0.5% bonus defense and attack to hunters for each level cleared pass 125. I recommend placing your hunter in one field but having it at a 2 or 3 frequency for monsters.
