Hymn of Hope
5min CD, 8% mana, must channel
this sounds really rubbish, plus for spriest, this is a holy spell and you need 32% base mana to get back to shadow form.
Hymn of Hope
You recite a Holy hymn of Hope, restoring 2% mana every 2 sec to all party members within 40 yards. Lasts 8 sec. The Priest must channel to keep the hymn active.
