Dire news to all World of Warcraft raiders. The Zanza buff will no longer last through death once Patch 1.11 is released. It is already implemented in the Test Servers. It will now be treated like any other non-flask consumable, which disappears upon death.
Seismics: “Spirit of Zanza no longer persists through death. However, the cost has been reduced from 3 tokens to 1.”
