FFXIII Long Gui using Death to hit 999,999 damage

Vanille 3162 Mag, Fang 2645 Str, Sazh 2590 Str
All are lvl 5 com and lvl 5 rav
Here is a video showing how you can kill a Long Gui without having lots of tier 3 weapons.

I have other videos showing how to kill them with lower stats or how to kill them fast with high stats. Just click on my channel for more info.

The three keys to the fight are: 1) use the summon to knock it off its legs right away. 2) use poison early as it takes a lot of hp off 3) vanille's death trick which will do 999,999 damage if you switch paradigms from sab to com before the spell is completed.
as you can see, I put a tier 1 weapon on fang just to emphasize the point that vanille does most of the damage.
paradigms are:
vanille/fang/sazh
sen/sen/sen
sab/rav/syn
rav/rav/rav
com/com/com
sab/com/com
