Also, that chardev build is really bad.
The rings of concentration are not worth it. At all. One should be Advisor's Band, of course, and the other one should almost always be either Sylvanas or Lavishly Jeweled.
Also, I always tell people to watch out for 'enchant mixing' - every time I see it, it seems, people do it wrong. In this case, it's having 7mp5 to chest and 9 stam to bracers. Math time!
If you want to get a mix of stam and mp5, then it would be statistically more beneficial to swap these enchants:
Chest enchant: 150 HP vs. 7mp5 = 21.5 HP vs. 1mp5
Bracer enchant: 90 HP vs. 5mp5 = 18 HP vs. 1mp5.
What that means is that you're giving up more hp, per mp5, mixing enchants this way.
If you were to switch these enchants, you'd net an extra 60 HP for the cost of 2mp5.
So either do that, or just go all the way (7mp5 and 5mp5.)
