Add to Google Preferences →Broken Vessel item card: Effect and description
Broken Vessel is an accessory of the “Offensive” type. Its effect line reads “[Heavy Attack] Sha-Chi Combos that consume Sha-Chi deal 15% more damage.” The bonus applies only to Heavy Attack Sha-Chi Combos that spend Sha-Chi.
The card’s description reads:
“The ruined head of a puppet stands as a silent indictment of the Herald’s countless crimes. On the training groungs, he performed the forbidden art of Soul Displacement, forcibly imprisoning the consciousness of countless Mandate disciples within Vessels.”

How to polish Broken Vessel
Polishing increases the bonus without changing what the accessory does. Broken Vessel has a Polish 1 upgrade.
- Polish 1: “[Heavy Attack] Sha-Chi Combos that consume Sha-Chi deal 25% more damage.”
- Cost: 17,952 Remnant Dust plus a Tainted Crystal Shard
Quick Hand Zhang sells the Tainted Crystal Shard for 7,440 Remnant Dust. You can also find a Tainted Crystal Shard in the world.
What Broken Vessel is good for
Broken Vessel suits a build that leans on Heavy Attack Sha-Chi Combos, adding 15% damage to the ones that spend Sha-Chi, or 25% once polished. Seal of Dugu, an accessory from Crimson Forest, also supports Heavy Attack Sha-Chi Combos, but it does so by draining more enemy Sha-Chi rather than adding damage. For other ways to increase damage, look beyond accessories as well.
You have three accessory slots available from the beginning, so you can equip Broken Vessel with two other choices. The complete Phantom Blade Zero accessories list includes each accessory, its effect, and its location.
