1. Promethean Magic
2. Ley Walker
3. Magic Training
4. Perception
5. Archaeology
6. Unarmed Combat
7. Berserker Rage

My strategy was to whore up the magic range attacks or distract enemies with the summoned wrymling. Magic training and ley walker tap mean basically infinite mana. Unarmed combat so I could double up on orbs and go for maximum magic power. Ley walker teleport spell lets you get the artifacts that spawn on islands, which can then be cashed in for experience via archaeology. Archaeology + Perception to avoid traps, especially doomsday traps like thaumite nest and corruption fluid on later levels. Berserker rage to get through the first level.
