Scrubbing through my source, looking for what it'd take to switch skills and spells to an independant timer, I found this:
if( !str_cmp( cmd->name, "slay" ) )
char *tmpargument = argument;
tmpargument = one_argument( tmpargument, tmparg );
if( !str_cmp( tmparg, "Samson" ) )
send_to_char( "The forces of the universe prevent you from taking this action....\r\n", ch );
Yes, this was in interp.c - The command parser
Samson! How could you?!
