Which level 1 monster do you like the most in Heroes of Might and Magic V?

They compare the strength of different creatures in single combat, in weekly progress, and so on. Just remember the final battles: which of the 1st-level creatures are useful and don't die from a single attack? Skeletons, assassins, and goblins, because they don't attract much attention, so they are effective when combined with other units! Imps die after the first attack on them or in response to their attack (but they have a good mana supply, especially if they have a ring of speed or undead artifacts, so it's very important to attack them!). Gnomes are tough, but they are only useful for protecting archers! Dryads also die instantly from a mass area attack!
