Remains in Play. Place a small (3") blast template so that its central hole is within 12" of the caster. Whilst in play, the template does not move and is treated as dangerous terrain. Enemy units that end their movement within 12" of the template must immediately make a Panic test. Those that fail will Fall Back in Good Order or flee directly away from the template. Those that pass (or that do not have to make the test) become subject to the Impetuous special rule whilst they remain within 12" of the template.
