When used, the Path of Cenarius enables players to travel with a wake of flowers at their feet. This effect lasts for 5 minutes and is usable in all forms (apart from a Druid's Flight Form). The only actions that can cancel it are mounting, dying, or clicking off the buff itself.
Each loot code rewards the player with 100 charges of this item. Path of Cenarius can be stacked up to 250.
