I think the best way to start the game is to get the Energy Burst spell under the Mage section. Use that spell for all your fights while you try to unlock the Death spell under the Demonic section. Once you get the Death spell, everything becomes much faster. Also, using the Blood Siphon spell is a great way to heal yourself + damage the enemy.
