inferno is better than treebark. Treebark is better than the BoA chest. Spirit is nice, but not worth losing stats for. 100mana is a fail enchant. 4 stats is better than 100mana and 100hp is generally better than 4stats. If you want a mana build then get inferno with 7mp5, over a 3min fight you will end up with about the same mana but you will have 19spell power more at the cost of 6stamina, 19sp>6stam anyday. Over a fight that lasts longer than 3 mins inferno + 7mp5 will give you more mana.
