FF13 platium trophy complete

Just completed all of the trophy for FF13 game,
Game play hour 95 hour.

The boss at the last mission can be simply take down by only using Bio magic.
Just poisoned it, and than change to Defender and Healer and watch its hp decrease in good rate, use Bio again when the boss remove the poison state, and than cycle and cycle. And this is also the way to get 5 star on that mission.

I never saw any boss character in the game can be poisoned to death before, LOL
