Can anyone tell me EXACTLY how the Dragoon's 2hour Ability works?

[Lone Dragon]

I've heard bits and pieces here and there, but nothing definite.

How long it lasts.
What Abilities it can have.
Etc.

After you activate your 2 hours,

1. Your dragon comes out
2. Your dragon will attack with you
3. If you use weapon skill, your dragon will also(friend told me)
4. Your dragon won't disappear until he is dead.
5. If your dragon is dead, you can call him back again after the time limit is up.

Thanks a lot.
I've also heard somethings about your sub-job having an effect on him, do you know anything about that (rumor maybe)?
