Battle Prompt is a different type of prompt coded by Remcon, one of my coders.
If you have any questions on this, feel free to ask me, or the smaug mailing list.


In comm.c
search for display_prompt
and you can change it all with this or just add case 'C' case 'c' case 'e' 
case 'E'
which every you want to do :)
