The skeleton is a level-one creature of the Necropolis in Heroes of Might and Magic IV. Skeletons make a moderately good screen for your heroes because of their enhanced ranged defense. While no stronger than many level 1 units, they can be formidable even late-game because of their numbers; if a Necromancer picks up the Necromancy skill fairly early and doesn't immediately raise it to Expert or better, he can accumulate a terrifying number of skeletons before very long - hordes of over 1000 are possible.
