I'm in the process of creating a comprehensive herbalism guide. During the process, I came across some outdated links:
In Briarthorn, there is Imbue Chest - Lesser Spirit
In Bruiseweed, Imbue Chest - Absorb
In Earthroot, Elixir of Tongues, Imbue Weapon - Beastslayer and Imbue Cloak - Minor Resistance
In Mageroyal, Imbue Bracers - Minor Wisdom and Elixir of Tongues
Additional research turned up the following:
Formula: Imbue Chest - Spirit
Formula: Imbue Cloak - Protection
