A slide is coated with a slick substance and designed to send characters tumbling, offering quick transport at a price.

    Effect: A slide is difficult terrain. A creature that enters a slide square must make an Acrobatics check. A creature that fails immediately moves to the end of the slide, falls prone, and ends its move.
    Usage: Use a slide with skirmisher monsters that can handle the Acrobatics checks and take advantage of the slides to move around quickly.
