Note: Small widgets appear at the bottom of the window to indicate health and combat status. A caution indicator appears whenever one of your group member's health drops below 75%. A combat indicator appears when you enter combat mode. In addition a combat frame appears around the health globe and player's name when you are in combat mode. Colored "dots" are used to indicate group member's health status. Health status colors in order of highest to lowest are blue, green, yellow, red, and blank when dead or not available.
