No longer increases the Mana cost of skills by 50%. No longer grants 30-40% increased Spell Damage. Now causes Notable Passive Skills in radius to be transformed to instead grant 10% increased Mana cost of skills and 20% increased Spell Damage. Now has a Small radius. Existing versions of this item are not affected by these changes. It is now also limited to 1, which does affect existing versions of the item.
New version has a mod +(5-10) to Intelligence [Undocumented This change was not documented by any official sources. It was discovered through player testing or datamining.]
Fevered Mind now increases the mana cost of skills by 50% (from 100%), and grants 30 to 40% increased Spell Damage (from 20 to 30%). This would affect existing items, except since they're all corrupted, you can't reroll them. Blame Atziri.
