This tower is only available after you have completed the game and obtained the airship. Without the airship, the tower is inaccessible. Tower of Agito is similar to other survival type dungeon run in that you face of against waves after waves of enemies at each levels of the tower. At the end of the dungeon run, you are rewarded with a random item. Before you begin, prepare your character as much as you can. Maxing out their level is recommended. Rem, being the most OP of all the character, is the one I will be using for this run. You can try it with the others for extra challenge if you like. As for equipment, SP Crystal is recommended. You can choose between Akatoki Amethyst or Blessed Armlet depending on your play style. Akatoki Amethyst allow you to clear the enemy quickly but you will die if any of them ever hit you. Blessed Armlet allow you to survive a few hit but takes a while to kill the enemy. Now on to the enemy itself. Stage one consist of 100 Tonberry while stage 2 consist of 100 Coeurl. The strategy for both of them is very simple. Quick cast your Fire BOM II to insta-cast Firaga BOM II. If they don't die to the initial damage, the lingering flame will burn them. Have patient and you will survive.
