hello guys

as of now, i have myself lvling my ranger for AA build, but i got some questions on what comes to reroll

1)if i supposedly buy a 32 point build, and reroll my char, will it restart as a 32 point build to set all points again? or will it just reset back to lvl 1?

2)what benefits does reroll gives?

3) i saw at store a item for lesser reroll or something of the sort, whats the difference between that and the greater reroll, or so i saw on some other threads?

4)do i need necessarily to buy it with turbine points? or can i get it from some quest?


edit: i know it may seem out of topic but another question hit me, the tomes for atributes, can we only buy them at store? or do we get them latter on at game from quests and so on?

well, thats pretty much my questions, thanks for future answers^^
