I had a pretty powerful character build, so I thought I'd share.
Skill Points: 20 pts Melee, 8 pts Fortitude, 4 pts Electric Magic, 10 pts Necromancy
Warrior (first): Weapon Shield talent
Necromancer: Life Spike, Cannibalise talents
Storm Mage: Thunder Clap talent
Barbarian: Rage talent
Used heavy and medium armor, long sword. So, basically a ShadowKnight build if you consider Thunder Clap a fear spell. Rarely needed to use items.
Note that the game saves your gear and level only after returning to town. You can save your progress in a dungeon if you want to take a break, but if you die, you go back to the last time you used your wings.
