Fired whenever a unit's mana is affected.
This event may be sent more than once to represent the same change if the affected entity can be accessed through multiple UnitIDs. For example, two UNIT_MANA events will be sent for raid party members who are also in your party group.
UNIT_MANA events are sent for raid and party members regardless of their distance from the character of the host. This makes UNIT_MANA extremely valuable to monitor party and raid members.
