When Casting Ward of Thorns the Mage scratches a line in the ground. This can be as long as 10 Legats per Level, but the Mage must draw the entire line while casting. When the line is complete a wall of twisting grey thorns, bare of leaves, bursts from the ground along the line, rising to a height of 2 Legats. The thorns inflict D6 Lethal on anyone trying to push through them. If you try and do so roll Physical vs. 15. On a failure you take the damage but do not force your way through. Cutting a gap sufficient for a Keldian requires 14 damage with a cutting or chopping weapon against Defence 10. The wall lasts 10 minutes in the Light or Dark side or 30 minutes in the Twilight Lands.
