mspecial.c, dragon

Replace the function with:

bool dragon( CHAR_DATA * ch, char *fspell_name )
{
   CHAR_DATA *victim, *chosen = NULL;
   int sn, count=0;

   if( ch->position != POS_FIGHTING
       && ch->position != POS_EVASIVE
       && ch->position != POS_DEFENSIVE && ch->position != POS_AGGRESSIVE && ch->position != POS_BERSERK )
      return FALSE;

   for( victim = ch->in_room->first_person; victim; victim = victim->next_in_room )
   {
      if( who_fighting( victim ) != ch )
         continue;
      if( !number_range( 0, count ) )
         chosen = victim, count++;        
   }

   if( !chosen )
      return FALSE;

   if( ( sn = skill_lookup( fspell_name ) ) < 0 )
      return FALSE;
   ( *skill_table[sn]->spell_fun ) ( sn, ch->level, ch, chosen );
   return TRUE;
}

Dragons ( or other breath mobs ) would tend to breathe on whoever was listed first in order by the occupants of the room. This makes the choice a little more random based on who is fighting the mob.
