Have some of the same powers
In addition, and perhaps most important, many beneficial group spells Tabula Rasa Gold and abilities used by a group member will only extend to that group. Common examples include Paladin auras, Shaman totems, and a Warlock Blood Pact. These spells and effects must be considered by the raid leader and assistants when forming a well-balanced raid.
A raid leader has special tools to assist in raid organization, structure, and communication. The raid leader can move people between groups at will, add or remove raid members, and use raid alerts and a special raid leader channel. Raid leaders can also promote assistants who have some of the same powers.
