Vision de Bahamut - Défi - 12/05 au 26/05

Cecil Our beautiful and very mainly tank prove to be really useful here since he can use Focud to give your team the SPR you will need.

An Healer Y'shtola/Refia w/ DC. It's really important you have an healer capable of surviving the megaflare and that can DC curaja. You will need it to top yourself off.

Element Resistance Marie and CoD are very useful for this trial, as their lovely guard/Omni veil are NOT green magic and Bahamut will spam the shit out of a billion element.
First few turn

First: buff SPR with your Cecil and DEFEND with all your other unit, Bahamut can, and will kill your unit through focus easily with Megaflare, there's a huge chance Cecil will die if he does not have a really high SPR.

Second: if you defended with everybody, you should have been able to survive, DC curaja with your healer to top everyone off, if your Cecil is dead, you can ressurect him this turn with Phoenix down (or another healer actually) or let him stay on the ground, Bahamut (from my 4 tries) won't do physical attack on the 2nd turn.

Third turn and forward: Keep buff up, the boss will start spamming element, I personally did not see a second megaflare.

At 40% he will take one turn before using Maelstrom which is a 99% current HP on your party, there's no way that I know of to reduce those damage. You have to heal through it.

After that, He will resume his normal billion element spamming.

Slowly chew through his health bar, while keeping buff up and running and you should be able to survive until he falls, don't forget to kill him with an espers for the pot!
