Boss Help

Actually, I don't know if this exactly qualifies as a "boss fight", but it's a pain in the ass that I can't defeat and I can't find any strategies for it online. The battle I am having trouble with is the one against two chimeras and one guado that you encounter shortly after reaching the Al-Bhed home. Any help would be greatly appreciated.

Do you have any Petrify Grenades? I know Guado are vulnerable, and I think Chimeras are too. A one-hit kill. ;)

Woooooo, it worked. Alex, you are the man. :D
