Now, necromancy in ROGUELIKES :
Adom is a amazing rogue like. IF you are into minionmancy, is not good but every class can learn necromancy skill however, only necromancers can fully master it, a lv 50 wizard which learns necromancy can only raise zombies and skeletons while a true necromancer can raise lots of different types of undead. Raising the dead is a "chaotic" act and messes with your char alignment, it also require corpses and damages your mana attribute(after some time it regens). There are also a variation. White necromancy. Only available for mist elves of neutral and lawful alignment. Animates constructs like Homunclus, Statues and Golems instead of undeads.
IDK if some necromancer abilities like the vampiric hands on lv 25 for necromancer applies to white necros as I never reached lv 25 but other abilities like animating every corpse on sight without cost for temporary instead of permanent undead doesn't seem to be available for white necros.

- Rogue Empire WITH dark heroes DLC
This game has a necromancy in between ADOM and ToME4. What I mean by that? It requires corpses for PERMANENT minions but contrary to adom, not only humanoid corpses can be used for necromancy. The drop rate for corpses is much more generous and there are a hard cap in the amount of permanent minions which you can have which grows with level. At lv 1, you can only have two minions and they are basic skeletons, however, reaching the level 10 and picking the options to increase the number of minions, I could get up to 6 minions(4 permanent and 2 temporary) and in my first run got the options to use also skeleton archers, wraiths and ghouls. Ghouls are by far the most effective minion, they start weak and small but they tends to drain lifeforce from enemies and grow in size. There are also a spell to create corpse but it costs a lot of hp, only use if you have no other choice. You can rest to regain hp but the game has food/starvation system but is much more generous than ADOM.
New spells and necromancer abilities can be learned randomly in level up screen, and from scrolls, books and wands. Failing to learn a spell can have disastrous consequences.
The default AI of ranged minions is braindead but there is a perk which can be randomly chosen to make it better. There are also temporary minions. Contrary to the "non dark' magic users which only uses mana, most offensive dark magic spells from necromancers also costs hp and necromancers are incredible frail. So you are essentially disarmed without minions.
The game also has abilities to become a Lich and a vampire. No, Lich doesn't have a phylactery like from ToME4 and is a very rare option in leveling up. Lich transformation in the game
