Which monster do you like the most in Heroes 5 (level 4)?

As much as it pains me to admit, the Vampire is the best unit at level four. It restores its own hit points after a powerful attack, has high initiative, and, being undead, many spells don't affect it. If there's a strategy, it can reach the enemy in one turn. A very strong unit. Mages also deal a lot of damage (although they might hurt allies. But to avoid that, don't attack if you see it will affect them, just cast spells), and Druids are good spellcasters. Berserkers are too fragile and are indeed weaker than Furies. Although they deal decent damage with Ranged attacks. Griffons and Lizards are good, but not as much. Gemonesses and Shamans are weak. Still, undead are stronger here!
