The Grey Seer adds +1 to his armour save, normally giving him a 6+ save. The Grey Seer can casts spells in a 360-degree arc, measuring a spell's range from any point of the Screaming Bell's base. The Grey Seer can draw line of sight for spells over the heads of the unit pushing the Screaming Bell.

The Grey Seer may use Verminous Valour to refuse a challenge, but is not removed to the back of the unit. The Grey Seer is not moved but cannot fight or be attacked for the duration of that engagement.
