The Necromancer's Path.

Well, with Giovanni, everything is simple – he has little mana, so the main thing is not to rush and defend until he spends it, and then calmly counterattack. And in the early to mid-game, his avatar under the celestial shield can almost single-handedly decide the outcome.
The plot is good; I personally like the borrowings from the lore of the sixth game (the only good thing about this game). The soundtrack is also good, but I hate dwarves. I really hate them. (I've played Ice and Flame three times)
