This goes along with my Battle Axe (http://www.stick-online.com/boards/index.php?topic=1797.0) idea: the Skeleton Warrior! This monster can go in any version of SO, but I'll talk like it is for SO2. It is like a Skeleton, but darker in color and wields a Battle Axe. It is slightly slower than a Skeleton, but it has higher health and greater attack power. It attacks with an oversized axe. The Skeleton Warrior's cooldown is kind of large, but it can still be a pretty tough foe. If for SO2, Skeleton Warriors can be added in with those skeletons to the right of the temple, with a slightly smaller spawn rate. They can drop everything Skeletons drop, but have the Scythe replaced with the Battle Axe (smaller drop rate as well).
maybe they could spawn like ba except at temple spawn rate wise
