After trying for quite some time (actually my 4th try ever lol), we manage to dethrone The Good King Moggle Mog XII. It took us 25% echo and almost the whole raid time, but by the twelfth we got it done.
You can't hear it because I didn't record the TS, but at the end where he does his final cast I start going ballistic telling everyone to kill it lol.
I managed to score the Ribbon of Casting too~
Now its time to slay Ramuh EX!
