With a 20 wizard necromancer, all magic items allowed (with the exception of sentient items) with the three attuned as usual, by RAW:
How many undead can you maintain control over with a 100% success rate at the same time? I want to exclude Finger of Death, and undead created by your own undead — just direct ownership.
I'd like to know how many of each tier of undead I can control. So from highest power to lowest power undead, in terms of CR, how many of each can I control? For example: mummies before ghasts, before ghouls, before zombies, etc. Meaning, if you could control 2 mummies or 4 zombies, take the mummies first, then move down spell slots.
