Currently healers have 50k mana in their base mana pool. And the enchant gives 3000 extra mana (extra 6%, 50000*0.06=3000).
Spells consume a certain % of max mana. However, the enchant does not change the cost of spells, neither it changes the mana regen rate (at least according to what DejaCharacterStats shows).

Mana regen is % based right? Does anyone know if this will increase mana regen?
