Verb:CURSE

The curse verb can be used by itself, which would look something like:

>curse
You curse the day you were born.

Additionally the curse command ties in with the Curse (715) spell.
CURSE HELP shows how this aspect of the verb works:

 Usage:
    CURSE [target] [cursename]

 For further information:
    CURSE LIST

    CURSE HELP POWER

 Your cursing power is 99.

CURSE LIST shows what curse options are available to a sorcerer. Information on each curse can be found with CURSE HELP {cursename}. The asterisk-marked curses are those that the sorcerer can utilize. As the sorcerer grows in power, so do the curse-choices.

CURSE HELP POWER refers to the sorcerer's ability as it pertains to the Curse (715) spell and to what curse-choices are available, thus it can largely be ignored when it comes to the casting process itself. Type CURSE HELP to find your current power.
