The skeleton warrior is the upgrade to the skeleton, the first-tier creature of the Necropolis faction. It can be recruited from the Upgraded Cursed Temple. With increased attack, defense and speed, for just 10 gold more, this upgrade is worth the cost. The disadvantage is that, if the Hero knows Necromancy, new Skeletons will show up after every fight, which means that Skeletons will take up two places. If there are no vacant slots in the hero's army, and hero has Skeleton Warriors, the Necromancy skill will spawn Skeleton Warriors, but at approximately two thirds of the number of Skeletons who would normally be raised. Choosing not to upgrade them will give the hero an army that's more numerous, but with worse stats.
