30 - Vancian Magic - Cast magic like the wizards of old. Your next 20 spells do not use Magicka and are twice as effective. When you run out of spells, you are unable to cast spells until you rest by sleeping at an inn or in your home.
50 - Quadratic Wizard - Whenever you recharge your Vancian Magic spells, you gain 1 additional Vancian Magic spell for each 10 points of base Magicka.
70 - Dungeon Master - Whenever you recharge your Vancian Magic spells, you may choose less or more spells in exchange for increased or decreased spell effectiveness, and/or choose one of three metamagic enhancements. Your choice remains in effect until your next rest.
