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

Does anyone know about the skeleton upgrade in Tribes of the East? Tell me how to make skeletons able to cast Verdict.

They are strong, but I built archers. From the alternate upgrade, I only liked the spirits. Banshees are also good, but Messengers are better, thanks to their attack, especially when your strength is running out.
