Acheron Kit in Honkai Star Rail explained

Acheron will be an incredibly powerful character, and she is the first character in Honkai Star Rail to not require Energy to cast her Ultimate ability.

What are Crimson Knots? (Acheron Debuff)

Acheron’s Crimson Knots are a passive debuff inflicted on enemies by Acheron. They will be “removed” by Acheron when she uses her ultimate. Essentially, Crimson Knots mean Acheron will deal bonus damage to enemies she has already targeted this battle if she attacks them during her Ultimate.

If you kill an enemy with Crimson Knots still on them, Acheron’s talent will transfer them to the enemy with the most current Crimson Knot Stacks, so they won’t be wasted.
