Heroes 5 - Inferno Creatures: Familiar - Imps are a quick level 1 creature who can deal good damage. Though hampered by their Hit Points, numerous stacks of Imps can be a great annoyance to enemy heroes. They are also fairly cheap. While the Familiar is a decent upgrade, and proves to be even more of a pest than the Imp, their cost is almost doubled, making it the most expensive level 1 walker. They do however deal good damage, and have a great initiative value, though their speed is rather low.
