As the game progresses

It starts to get really challenging to the point where you almost always need party members to do the dungeons effectively, I never thought the game would get so tough and the character I use is a summoner which isn't very combat savvy but she can summon up minions that can do the hand to hand combat for her.  I finally beat all the dungeons in the place where I currently fight called Sky Tower but now I got a bunch of quests that seem impossible to do alone, I hope I can get a few buddies to work with me for it.  I can't wait to reach lvl 30 so I can get even stronger summon monsters to fight for me then the game won't be too tough for me.
