The spell Ice Arrow is a second circle spell which inflicts 50 points of magical damage. If the caster uses a scroll, he needs 5 mana and a magician who uses a rune to cast the spells, needs 10 mana. A rune for this spell in Gothic 2 can be found in the Valley of Mines in the neighbourhood of the stone circle in the southwest. From the circle head, towards the dead end. You have to dispatch the two skeletons which are close to the rune. From chapter 3 onwards, the rune is also guarded by a seeker as well, but killing the seeker is optional.
