GM'S i need help :(

So my problem is, when i got the quest in act 1, where u have to open or unblock the road to get to the Emperor's road. when i went back to town i didn;t know about the gems and so i bought the passive skill that wasn't compatible with my class. so the only way i can pass that quest if u guys can plz send me my passive skill for my class. I'm a lvl 15 Marauder, if u cant its okay, maybe there is another way of completing this, instead of starting another toon. which would really suck because spent alot of time on this one.
