HB

The HB channel is used to arrange and discuss HEROBATTLES. This channel is
only available to heroes, and if you have a gag, you cannot speak on it.

The channel is only available when a god has it turned on. Type HB by
itself to see if the channel is turned on, and which gods are listening to
it.
