Ok just needed a few tips from any mage players.

I use the regular setup:
Fireball
shield
Lightning
Heal

I JUST started using curse.. Now after reading its description, incoming damage is reflected back at its caster. So why did a 1v1 with a rouge go wrong? Curse is up and she/he is just steady shooting me and I die. I ask them and the reason is she/he has a lot of hp. I inspected the player when we got back into town and they only had 3600..

So basically im just looking for the most effective combination of skills, how i should be using them.

Thanks.
