My great suggestion here is spider jockey. It has spider and skeleton on top of it (spider).
if you upgrade them, they will be all affected by an upgrade by monster's own upgrade.
Example, if you max it to level 5, it will be invisible spider and level 5 skeleton (without horse)
But the spider's movement is still fast so it's a double trouble. But if the spider is killed, it will remain as skeleton, movement is as slow as a normal skeleton
Level 5 spider jockey
1. Health: 1000 (skeleton, also i know it's a nerfed health)
2. Health: 200 (Spider)
3. Price: 400 - 1000
4. Immune to: (Monster's immunity)
5. XP reward: 50 - 100
6. Speed: 2.0 (spider jockey), 1.6 (skeleton)
Spider jockey in level 1 (Please don't include the bow)
