starting up again, couple questions

[Keeblar]

Hey all -

I played for a while back in september - octoberish. Well, some real life issues got in the way of gaming (starting a new career, moving) but I want to get back into the game.

I am starting as a naked level 13 troll shaman (corpse rot... didn't think I would have time to play again turns out i do) and I have the follow question:

back when I used to play, when I did the greater lightstone quest, the book that I got wouldn't sell for anything. Does it give you PP now? I feel like it did for a while, then all of a sudden it didn't so i stopped hunting wisps. My memory might be off. Because if this quest gives plat again I can easily dot-kite wisps and try to rebuild my toon.

thanks in advance!
