My Necromancer's Class Can Only Support One Summon [A Necromancy LitRPG]

If you like this story, then don't forget to drop a follow or a rating to help me out ============== Ha~, since when was necromancer's so blend?  Growing weary of the tired trope of swarming undead legion, he yearns for a single, unparalleled minion.  "Imagine it! One minion strutting through the battlefield like an undead behemoth, unstoppable in the face of puny heroes! A minion that could tank a thousand attacks, and how 'bout this – the thing actually learns some skills! These minions, they're just hanging around, and swinging their weapons, auto-attacking the heck out of a dragon. How awesome would it be if your summon could learn Active and Passive skills,  maybe even use equipment's. But nah, they're like, 'Let's just level the skill up increasing their health with it and expanding the quantity of the same skeleton.' That's cool, right? No!"
