In the magic phase of each turn, the banner unleashes D6 lightning bolts with a range of 24". . Each bolt strikes the first model in its path for 1 S4 hit. Can also be used against foes in base contact with the bearer. No armour save allowed, even against magic armour.

This is a spell and may be used when you have the opportunity to cast a spell in the magic phase, just like any other spell item or spell.
