Interlude's documented cursed-weapon interactions.
Interlude adds Blood Sword Akamanah alongside Zariche. Expiration is 24 hours after the last player kill. On bearer death, dropping and disappearing each have a 50% chance. Acquiring the other sword consumes it and increases the equipped sword by one level. A hit between bearers removes the target’s CP.
Bearers gain Void Flow and Void Burst. Both have an initial reuse delay when the sword is acquired, so pickup does not guarantee immediate skill availability.
Historical descriptions disagree about the level boundary for protection and whether Hero skills can affect a bearer. The Interlude changes reviewed here do not settle those conflicts. Do not plan an attack around an assumed exact boundary or immunity.
