First of all, huge shout out to aerial for his guide format which is just too good not to copy. http://forum.median-xl.com/viewtopic.php?f=40&t=22675
The goal of this guide is to show you my personal take on a mana sorc in median xl sigma 1.0. This is how I personally chose to build the character and it has worked out very well for me. There are lots of different ways to approach building a sorc and some may be more efficient and min-maxy than what I chose to do but, having said that, at no point did I feel that I was struggling on this character in any way against any content so far. The character has done all challenges, rifts, and dungeons at the minimum level they could be done (up until its current lvl 120) and had no real problems with any of them.

HOW TO PLAY
I usually start out with a chronofield then spam arcane torrent on most trash mobs. Use mana sweep to gain back mana when needed. For single target I dump my mana with either antimass or force blast then spam immersion. The idea is to achieve enough mana regen so you don't run out of mana when spamming immersion so you can remain at low mana for maximum damage.
