How do you beat bituitis in Final Fantasy XIII?

Answer 1

Bituitis, the winged cie'th on pulse is the one you mean, right (the target of mission 7)?

If so, here are some tips.

- Equip lightning resistant accessories, they will make a huge difference. Spark rings, and their big brother, i think its called fulmen ring. In the central expanse youll find another accessory that will sometimes absorb the lightning element (there is also one for fire, ice, wind, and one or two more) Make sure your leader has enough resistance to survive the lightning based attacks, they do a lot of damage.

- you could also put on plain magic resistant accessories, like witch bracelet

- this guy is sucseptable to imperil, the saboteur ability that increases elemtal weakness, since he has half way resistant, this helps.

Here are some of the paradigms i used (lightning, vanille, snow )

1) Commando, medic, commando

2) ravager on everybody

3) commando, sabeteur, sentinel

4) commando medic sentinel -

5) commando rav commando.

6)commando sabateur commando

Vanille has imperil, so i started with #3 till it stuck

Then i attacked him using com rav com to slow down the stagger bars rate of decline,

then switched to 3 ravs to fill some more and if low on health, used 2 coms and medic.

eventually youll fill his stagger bar, then i used either com sab com ( to try to put on de protect and deshell, and others) or just com rav com, to attack all out. Also, having com med com is great during staggers, in the case that you get damaged, you can still do serious damage while healing. Hope this all helps.

In short, id say lightning resistant accessories, mabye magic resistant accessories, and then a good set of paradigms.
