This one image is from a photo from the strategy guide's affix section. I guarantee no plot spoilers - it's just like looking at the affix section of Diablonut, except maybe more accurate.
What intrigues me is that it only lists 'Ceremonial Knife', 'Voodoo Mask', and 'Mojo' for the Mana Regeneration and Maximum Mana affixes.
Does this mean that we won't see things like Shields or Staves with the mana regen affix?
If so, then the maximum MP/S we can get from items is +42.
I'm inclined to believe that the above is true, because this strategy guide seems quite specific on what items affixes can appear on.
http://i.imgur.com/KXsHV.jpg here for example, you can see that some of the skill-boosting affixes like that of +% damage to Haunt can appear on Daggers, Spears, Bows, Crossbows, and Ceremonial Knives. Quite a bizarre array of weapons, considering that +% damage to Poison Dart only appears on Shields, Mojos, Bows, and Crossbows.
Also, typo with their section on Corpse Spiders - it says that it increases the duration of Blizzard. Lawl.
