Acheron is now like Herta and only needs 1 Nihility.
Her stacks are per debuff. So if a character applies 2 debuffs in one attack, that's 2 stacks.
E2 is each Crimson Knot stack reduces enemy def by 5%, and entire party EHR is increased by 100%.

This would make her ok. The only downside is that JQ would become much, much worse for her than SW and Cipher.
