imo best way to beat gravios is high grade earplug armor with a pierce bow u can still break the chest plate and do alot of dmg if u are a good shot like predian said bows can do just as much dmg as any oher weapon i like bows better 2 but im still hr1 and im haveing trouble find good gear for bows. Tip:when fightng gravios with a pierce bow try to shoot it in the chest,head,or the tail so the shot follows the tail to the spine doing alot of dmg.
