mission of Shamman

Alguien sabe como se hace la mision del shamman?.
Anyone know how to do the mission of Shamman?

which, the one where he wants ingredients to make the underwater potion? Most items can be bought in aeropolis, but serpents crest needs to be gotten from a cave deep in the lifewood. You need the ability to go into the dream realm.

That can be gotten from Gloria

ha, thanks you.

and as I get to the world of dreams?.
I have only to speak with Gloria?, carrying off something I have to see, because I already had tried before and failed.
I am using a translator, I speak Spanish, so try to interpret what I say.
from now thanks.
y como llego a el mundo de los sueños?.
solo tengo que hablar con Gloria?, tengo que llebarle algo?, porque eso ya lo habia intentado antes y no sirvio.
estoy usando un traductor, yo hablo español, asi que intenta interpretar lo que digo.
desde ya gracias.

1 talk to gloria.
2 go to save crystal, remove everybody but Mardek from your party and go to lake qur. Talk to Elwyn and let her join. Make sure she is in your party.
3 go back to gloria, she will join too, and talk about the dreamcave, which is north of the town, and will appear on the map.
4 Go to dreamcave, if you get the item there it makes dream world experiences easier.

Muchisimas gracias, thanks you so much.
