The Gist: If life as a mage was a little too boring, unlife as a necromantic archmage is certainly a blast. This is mainly because the local village has a steady supply of armed warriors on tap to send marching up to your doorstep each day. Ultimately, they're merely cannon fodder for your dark amusement. From atop your skull tower, you can drag your finger to string together bolts of chain lightning, draw circles of hellfire, freeze enemies in place, and perform other magical feats. After you've stripped the invaders of their souls, you can use their essence to purchase new nefarious spells. Good times.
