If I get the Glutton for Punishment Trophy, will I get the Q - Force Champion aswell ?

How do I get the Loremaster Trophy ?

Do I have to use Libra on 100 different enemies ? Or is it something else ?

Help would be very appreciated.

Yes you need to Libra them and get their full information.

Alright. I wasn't really sure for that one. But do you know the answer to my other question ?

You'll get their info from just fighting them a couple of times, but the little time to libra is worth it over trying out properties.
It's not a trophy you're likely to miss in any of the cases, even before the main story is over.

ffxii didn't have trophies.

I think your talking about ffxiii?

Just libra everyone for loremaster

you dont need to use libra, if you kill lots of the same monster you'll end up getting all the info on them. i must've used libra once or twice in the whole game

R&C dunno anything about the game but I hope this helps
