Help [FFX] Spherimorph

[Dragon Shadow]

I'm currently stuck on this boss which looks like a big blob of water called Spherimorph and I can't seem to figure out what form of attack actually hurts it. It looks like magic attacks just give it more magic and then it keeps saying something about it's weakness but It's not obvious to me! Can't figure out what it is! Can someone tell me what I have gotta do to kill it, what form of attacks? and which characters should I be using? I currently have Lulu, Yuna, Wakka and Tidus.

You can use magic, you have to use the opposite of whatever it attacks you with, once youve hit it, it 'shifts' so it will then use a different magic whicgh again , you have to use the opposing element. It hits you with fire you hit it with ice. It'l jsut absorb all the others and physical attacks are shite against it.
