Help Tick

Many of the game actions are based upon interval timers, including
combat, most autonomous monster actions, hp/mana/move regeneration,
spell duration, weather, and area resetting.

Of these timers, the hp/mana/move regeneration timer is popularly
called the 'tick'.  Ticks on this mud average 30 seconds of real
time, but the actual amount varies randomly from 15 seconds to 45
seconds.

Area resetting happens roughly every 3 minutes if no one is in the
area; less often (15 minutes) if some one is.  Also note that
objects lying on the ground will not be regenerated if anyone is
in the area when it resets.
