The Necromancer has 64 Legendary Aspects to choose from in Diablo 4, when Imprinting Rare or Legendary weapons at the Occultist. While 41 of the Aspects are exclusive to the Necromancer, a further 23 are available from a generic pool. Whereas every single one of the Aspects is potentially available by extracting it from an item, only 35 of them are readily imprintable from the Codex of Power.
