Call Quake

With Call Quake, the very element of Earth itself is used by the Necromancer and turned against the foes. Casting the spell will cause a heavy tremor, causing the foes to lose their footing, and being injured by falling rocks and stalactites. Aside for the injuries the foes receive, they also get horribly confused, making them prey for a surprise attack.

This spell is actually a special heritage from Lothian, only found in her belongings after her death.
