Alchemy for Hardcore
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.
