Could you please tell me where and (how) can I hunt Trickster and Deathgaze in Final Fantasy XII?

Trickster: The area to find it is Frozen brook 2 screens south of Bur-Omisace. This is like Gil Snapper. The first time you enter and it's there the guy from Clan Centurio will tell you.

If you exit the area and come back he won't tell you when it's there again so you'll just have to exit and reenter till it's there. You will probably want to venture in some to check it out as it can be semi-invisible(you can still see it's outline) but it will run around all over the frozen bank and most likely run into you. Deathgaze: Airship.

You should be able to find the client in any Aerodome. It's the son of the traveling family. What you have to do to find it is ride an airship and then talk to the boy again.

Each time he'll tell you it's getting closer and closer. By talking to him between flights your chance of fighting deathgaze increases. It'll still be random whether you get the option to fight it, if not just keep taking airships and talking to the boy.

Choose to fight it and then run ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
