Aura

Aura is a special light source because while it is blocked by VBL and can cast colored light, it does not actually illuminate anything. (An aura will not reveal hidden areas to a player, but it does act as a way to see how far from a token its aura extends).

The aura group name is not included by default and must be added by the user.

To add auras:

From within MapTool
Edit -> Campaign Properties -> Click the "Light" tab

The following is an example of the Aura group as it might be entered.

Aura
----
Aura Med Red 5' threat : aura square 7.50#55333
Aura Med malign 30' : aura square 32.50#330033

In the first entry "Aura Med Red 5' threat" is a descriptor and has no effect upon the light.
The information after the colon defines the light.
"Aura" is the type of light.
"Square" defines the shape of the light.
"7.50" defines the range of the light.
The number preceded by "#" is an RGB value for the color of the light.
