Event:UNIT SKILL

Fired whenever a units secondary 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_SKILL events will be sent for raid party members who are also in your party group.
UNIT_SKILL events are sent for raid and party members regardless of their distance from the character of the host. This makes UNIT_SKILL extremely valuable to monitor party and raid members.
