Profession notes for the crafted tools, material flow, and choices that fit this class's leveling route.
Tailoring provides bag space first and cloth gear upgrades from materials already dropping on the route.
Water, bandages, buff food, and healing potions all need Priest bag space. A Mageweave Bag around level 35 lets you carry the supplies together. Tailoring makes that upgrade predictable.
Class profession defaults, alternatives, and the tools each package adds to a difficult route.
Default: Herbalism plus Alchemy. Priest should begin a pull with mana above 80%, full health, and Fade available. Alchemy helps maintain that baseline across a long session. Alternate: Tailoring plus Enchanting for the caster loop. Choose Mining plus Engineering for dungeon-heavy routes.
Potions and elixirs give you recovery, movement, and a reliable use for the herbs you gather.
Priest trouble often starts several pulls earlier, when mana and health both slip. Carry Mana Potions for a long stretch, Healing Potions for a health bar that cannot spare a cast, and Elixir of Fortitude for a dungeon band. Start the next pull with those options available.
