The class seems great. But actually is horrible. There is a sudden massive failure condition where if your protective spells fail, you are attacked by your own undead familiars who truly hate you. They won't act irrationally against their interests to help you.
For example, they get a familiar who is an undead spirit (similar to maybe a Druid). The undead spirit (controled by the DM) would prefer to kill them but can't because of a protective spell ritual talisman they cast. They either punish the spirit with pain to get it to do their bidding or get a spirit who also desires revenge against their enemies. The necromancers spell list actually mostly protective and support spells, just used for horrible purposes.
I want to make a custom DnD class based on (https://en.wikipedia.org/wiki/Kodoku)(https://en.wikipedia.org/wiki/Inugami). The basic premise is that it's a necromancer who can summon the dead (who can't. So.Easy.), but has trouble controlling the dead (with whom they bargin) and must result to protective talismans to coerce the dead to do their bidding. Their undead hate them and want to kill them and seak to escape their control. A support class like bard that works more like a wizard in that they prepare spells.
I tried and failed to explain to my friends why I want edible pine cones (https://www.etsy.com/listing/1316599746/pine-buds-pinus-sylvestris-100-natural) for christmas.
Emotional contagion needs to be managed.I don't want to discourage people from talking to friends about their problems, but we need to discourage people from venting emotion in public spaces near other people. Every day I've been at a cafe and had to sit next to very emotionally charged conversation.
