Actually you're both wrong, he asked for official conquer commands and yes, there is commands on conquer.
/addeffect
/break
and so on.
@threadstarter : Seach for something like 'client commands' in conquer section, you should be-able to find them.
P.S You probably need Futures multihack to use them because when you're using it you can enable the commands. (Or you can modify your conquer.exe in order to do so.)
