The tactical display shows a list of mobiles and objects that are in the
room, with a number specifying the hit/hit_max ratio (in 10% increments for
non-group-members), with 'F' being 100% ("full") and - indicating less than zero
hit points - unconscious, but not dead. The names in the leftmost box are the
members of your group, with the color of the text indicating their base class:
wizards in cyan, rogues in grey, priests in violet, and warriors in yellow.
Mounts and pets are in green.  The center box lists other individuals in the 
room. The rightmost box lists objects present in the room, though it may
disappear if the other two boxes both grow to be two columns wide.
 
The tactical display also includes status information, including:
* Your character's name 
* The language your character is currently speaking 
* The spells and conditions (separated out as benedictions and afflictions)
affecting your character 
* Tactical Mannequin - each location changes colour as you get hurt there.
Your default color (usually green) indicates good condition, yellow indicates
you are hurt, red indicates critical damage, violet indicates that the
location is mangled (to the point where a limb can no longer be used), and
black means that the limb has been completely severed.  (You will find it on
the ground, with whatever was equipped on it still attached!)  

Additionally, codes after the health number now indicate further information:
- = Normal (non-hostile/not fighting) 
- = Hostile (waiting to attack) 
> = Currently being attacked (in melee) 
* = Fatigued (less than 30% stamina) 
* = Illuminated by Faerie Fire
* = Poisoned
* = Diseased
* = Blinded
* = Entangled
* = Silenced, Enlarged, or Reduced
* = Ability Score Reduced
* = Weakened or Held
* = Chilled (ability score drained)
