What mixed hero class of the Haven faction do you like?

No, it’s still better to start with Nature before Order. That way, you’ll get a Conjurer, which gives you a +20% bonus not only to creating everyone’s favorite illusions but also to summoning creatures :) An Illusionist is one-sided and has an incomplete set of skills compared to him ;) And after that, it’s best to go with Death. Then you’ll already be an archmage with a +20% bonus to all spells. You can create illusions or summon devils, cerberuses, or ice demons if you want :p
