Re: Powerleveling and Vanish/Doom
If you are level 18...I'm assuming you are still in the WoB. If so, go to the island you find Gogo at later on (in the WoR) You'll find monsters that you can get quite a bit o MP for to level up your spells - I think they give pretty good Exp too.
...others know more about this than I would. But it might help get more response if you say where you are at in the game... Personally, I waited until the floating continent until I powerleveled, but you COULD wait until later and get better Esper bonuses at level-ups. Your choice.
Fight, if there is something to fight for.
Never give in, or give up - but ALWAYS give.
Choose your battles wisely.
You only get one shot at life. Follow your heart.
