Foot of Gork (or Mork)

There's a massive green foot on the battlefield and it seems to be moving!

Remains in Play. Place a large (5") blast template so that its central hole is within 15" of the caster. Whilst in play, the template is treated as difficult terrain. The template scatters 2D6" during every Start of Turn sub-phase. Any unit (friend or foe) that moves through the template, or that the template moves over, suffers D3+3 Strength 5 hits, each with an AP of -1.
