~Do 9999 damage or more in a single attack~

This trophy isn't that difficult to pull off as long as you level your characters during the regular storyline. This can be done with either physical or magical damage and by a regular character or an Aeon. Keep in mind that elemental weaknesses do 150% of damage and can help you reach 9999. I personally earned this trophy in the Via Purifico by using Ixion's Overdrive against the Sahagin enemies.

This trophy can stack with Megastrike.
