How to get 2nd job in pvp?

I just played 1days in pvp, and i can use like range or monk as my 2nd job and i can get their skills, but i wanna use like elementalist but i didn't seen any of her skills , how to get it ? Do i need unlock that hero?

oe gain skills you should either do quests in pve, or gather balthazar faction to buy them, a good method for this is doing "Zaishen Elite". to gain heroes, it's basically the same thing, follow nightfall/eotn's storyline and they'll show up or you can again buy them with balthazar faction.
however when you "buy" skills and heroes they can only be used on pvp-only characters. when you want to use them on roleplaying characters you must buy them from a skill trainer, or us a tome..

Thx for ur answer but if i only play pvp , how can i get that skills? For buy hero?

you can also buy the pvp unlock pack from the online store (with real money)

Sounds good , so there are 2 ways for pvp player get that skills 1 is use cash other 1 is buy a hero ,right?

step 1) get balthazar faction from pvping
step 2) spend your balthazar points at a priest of balthazar for skills & heroes & item upgrades

Thx already sloved
