Remains in Play. Place a small (3") 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 D6" during every Start of Turn sub-phase. Any unit (friend or foe) that moves through the template, or that the template moves over, suffers 3D6 Strength 2 hits, with no armour saves allowed (Ward and Regeneration saves can be attempted as normal).
