Profession notes for the crafted tools, material flow, and choices that fit this class's leveling route.
Potions and elixirs give you recovery, movement, and a reliable use for the herbs you gather.
Alchemy supports Paladin's steady route with Elixir of Fortitude when gear is behind, Major Healing Potion when Divine Shield is unavailable, and Swiftness Potion for an exit. Keep those tools stocked instead of spending the bubble on every long pull.
Mining and Blacksmithing keep Warrior and Paladin weapon damage close to the level band.
Paladin's steady pace leaves room to gather before a craft is urgent. Retribution feels the level-30 weapon gap most. Mine ahead, make the weapon, and keep Divine Shield for an exit.
Class profession defaults, alternatives, and the tools each package adds to a difficult route.
Default: Herbalism plus Alchemy. Potions fit Paladin's deliberate pace. Alternate: Mining plus Engineering for dungeon multi-pulls. Mining plus Blacksmithing works when you accept the slower economy and bank ore before the weapon gap.
