No longer reduces mana at all while it's up!
This, along with Mind Over Matter, are now valid full-time buffs that an Enchanter can afford to keep up 24/7, instead of waiting until it's too late to fire it off!
This also stacks with the Cleric line of melee damage mitigation buffs, such as Rallied Aegis of Vie Rk. II. For even more protection, you can fire off Dimensional Instability once Rallied Aegis / Veil of Mindshadow have dropped. Altogether, these would give an Enchanter a much higher survivability rating in high-end melee encounters.
And, of course, you can stack on a Legion of Alendar Rk. II to provide protection against incoming spell/DoT damage, as well.
/cheer!
