Unlocking Mystic Regen?

Ok, when I go to the temple of balthazar and try to unlocl Mystic Regen for 1k balth faction, it has a little (PvP) after it.

Now I know that that means it's for PvP only so here's my question.

If I unlock the skill, could I use a dervish tome on my PvE dervish to unlock the PvE version, or do I have to go all the way to end-game to unlock it?

I'm fairly sure you unlock the PvP and PvE versions in one.

if you unlock it for pvp then use a tome on a pve toon you will be able to use it

It's the same skill, it just changes whenever you use it in PvP vs PvE, thus, unlocking it will enable you to use a tome to obtain it

it will work fine only reason it said pvp was you where in a pvp area and with the new skill derv balance thing thats way it said pvp but you can unlock
now in pve
