    Grease will knockdown creatures (falling them) each round.

    The dexterity check replaces this text:

    A creature can walk within or through the area of grease at half normal speed
    with a DC 10 Balance check. Failure means it can’t move that round (and must
    then make a Reflex save or fall), while failure by 5 or more means it falls
    (see the Balance skill for details).

    Which only applies if they are doing ACTION_MOVETOPOINT.

    On Enter:
    - Applies the 50% (half speed) movement penalty, always (no SR).

    I've decided heartbeat might as well do the knockdown.
