Form Training & fighting Xemnas
Don't listen to those people that say you have to be a level 70 to kill xemnas, I did it when I was a level 52, all you need is alot of high potions (I only used 4) and skill. You also don't need to use reflect or any upgraded forms of it, you only need to use all the reaction commands that you can and get in close to hit him. One more thing, try your best to dodge his moves.
To train valor, master and wisdom forms all you have to do is have ay least 6 drive gagues and go to Merlin's house in Radient Garden/Hollow Bastion. Next go outside and unequip all abilities for your team mates and move forward. Kill all the heartless then run to the enterance to the Baily (don't go up the stairs, go the other way) killing all the heartless on the way. Go the opposite way to the enterance to the Baily and kill those enimies then keep on going. If you have turned back to normal sora then change back. Jump down the side and head towards Merlin's House. Kill the last enemy and run inside Merlin's house and exit the world. Go back and repeat until all the forms are leveled up.
