Meteor Shower

Meteor Shower is a good attack spell in Thaumaturgy.

Spell Description
Using Meteor Shower, the Thaumaturge calls forth a shower of flaming rocks, which hurt everything around the caster, may it be friend or foe. It can be cast repeatedly, making the shower of flaming rocks much more devastating and deadly, since the caster himself is perfectly safe from it. However, because of its area effect, it's best not used in populated areas. The spell is ideal to deal with slow enemies like Trolls and Guards, especially sine it doesn't count as aggression.

Trivia

 * This spell becomes available after entering the Shrine of the Ancient Ones for the first time.
