Noob Cross Game Skills Question

Hey everyone. I've been playing Guild Wars for a long while, but I haven't done much to learn about the details of the game up until recently. I've been trying to make my builds more effective and useful, but I've ran into a couple of problems. I've seen builds that have skills from different campaigns and are only available from those specific skill trainers. I mostly play Factions, and I know it's possible to travel to the other campaigns. What I don't know is if it's possible to learn the other campaign's skills.

Could someone point me in the right direction? It seems a pain to have to run through three campaigns just for a skill or two.

If you own the other campaigns, then you can learn those skills. Just travel to the appropriate skill trainer and purchase the skill or, you can unlock the skill on your account using Balthazar Faction (1k for normal skills and 3k for elite) then use a tome to learn it.

Ah, thanks! I'll probably use the faction for the most part.

You can actualy purchase the skill from a Skill Trainer after unlocking it with Balthazar Faction.

More specifically, all trainers on the continent that the skill belongs to will offer the unlocked skill. For example, Flail is not available from trainers until nearly the end of the game. If you unlock it (doesn't matter how) then all skill trainers in Elona will offer it.

Now see, I didn't know that. Thanks for the info.
