New here: conjurer help

[Pnarpa]

Hello everyone

As the title already mentions: I'm new here and I need your help.

Questions:

1) What would be good to train in these skill trees for a conjurerer that wants to be a good support for his allies, but wants to be able to fight alone in battle?

2) I've read something here about reseting skill trees, so no worries if I mess up. But how does this work? I mean, when things have been reset, do I have to gather points again or do I just get them all back?

Actually, any helpful information about conjurers would be helpful. How to act in battle, how to train, buffs?, etc.

Thanks in advance
