About the Ninja Quests

So I've seen these quests, and they are well worth completing. I have some questions.

1) Is there any good place to hunt Phantom Trees?
2) How many badged can you turn in to be able to receive mesos/raven weapons.
3) What do you need to forge Raven equips?

Nevermind, misread.

Your best bet is to take a hidden street and hope that the trees spawn well.

In all areas, trees have the most horrible spawn so I'm afraid there is no area good for hunting trees.
As for the badges, I think you have to do quests from Taggrin before you can do that, not too sure myself...

I find running around the Twisted Paths has a decent bit of trees.
Watch out for Bigfoot and you'll have them quickly enough.

I think you need 100 badges to exchange for the mesos/raven weapon.
