dragonuff , remember that we will not reach lv 20.
Alodar , I mentioned this games only to show that necromancy is popular in those games.
And Vic, I strongly agree. Older editions allowed you to have way cooler pets. Pathfinder Wrath of the Righteous will allow you to reanimate bosses to serve you... Having only skeletons and the lack of OHK spells is why IMO 5e has the worst necromancy(don't know about 4e)
Mine is mostly how to mid max the most bodies on the field as possible in 5e alot you might not be able to do due to limits in BG3 such as not being able to get to level 20 or finding a ring of spell storing which is 50/50 if its in the game
My point is that back on 3.5e, you had a better progression. Animate Dead(3rd/4th circle) -> Create Undead(6th circle) -> Create Greater Undead(8th circle), so your low level character can only create few weak skeletons, a lv 20 necromancer in other hands can create few Devourers(CR = 11) and an army of weaker undead.

I love this type of progression.
On Gothic 2 - Returning 2.0, when you do the test and is accepted on circle of darkness, you can only create lowly weak skeletons. Then zombies on circle 2, then skeleton warriors with weapon proficiency that can block and attack on circle 3. On circle 4, you can learn demonology and create demons, by feeding your spell with demonic essences, you can create even tougher demons. On circle 5, you can cast army of darkness which creates 2 skeleton warriors and a skeleton mage armed with spear of darkness, a circle 3 spell.
Being only able to have skeletons from low level to high level isn't something which I personally like...
