sylvan vs inverno

So, we’ll be playing with my brother either in February (more likely...) or in June... I’m playing as Haven, he’s playing as Inferno. He’s playing as Marbas, and I’m playing as Wingael (or Ossir?:confused:). The map is Dragon’s Passage. I’m playing as the blue faction (in the bottom right corner), and he’s playing as the red faction at the top. He has a Sphinx on his side (and he’ll choose the 15k experience reward). We also have a Necromancer bot and our sister playing as a Warlock. I want to know what’s best to upgrade, which artifacts to take, what to build first, basically everything! It would also be good to know the tactics against the Elves, because they can also put up a good fight. And I don’t remember her hero, but I remember the heroine’s ability called “Witch’s Sabbath”...:smile24:
