Capture Signet questions

First I want to start of by asking where do you find the spell Channeling? I have a Mo/Me and this spell would greatly help...

Also can the Signet of Capture spell only be used once then its gone forever? Or can you use it, then buy the skill again, then use it again? Cause I don't want to use it up on a lame spell if it can never be used again.

You can use capture sigs as many times as you need it. Could even buy eight of them at once to fill your skillbar with.

you can get it from the yak's bend quest, as well as the lion's arch skill trainer and the ember light camp skill trainer

I'm looking for Channeling in Factions...or is that Factions?

Channeling is a Prophecies ONLY skill. This means if you do not have propecies, you will Never be able to get this skill

Thats pretty lame. Is there a skill simillar to channeling? I actually have P but am much further into F.

Get enough faction through Random arenas, Buy the skill there through faction reward, and it will be available at all skill trainers your guy goes to. ^^ (90% sure this will work)

and if you have access to kaineng center, theres a quest that will take u to lions arch, which is very good becuase that is one of the places that has that skill.

Not quite all skill trainers. Would have to go to Prophecies trainers, like Lion's Arch.

NOTE: unlocking it through random arenas only makes it available for PVP characters, not your PVE characters

No, it unlocks it for PvE characters. Once its unlocked its available at any skill trainer to buy.
