In the game but open only to testers for now, while they are tried out.
Every character can now learn two professions, whatever their class, just by doing them. Open them from the ☰ menu (More on a phone) or type professions.
Botany: herbs grow in about one room in ten around the world, easier ones in easier zones. Click Gather on a herb where you stand (or type gather); it takes a moment, then the plant is gone until its zone resets. Turn on Herbs on the zone map to see where they are growing.
Alchemy: mix your herbs into potions: healing from Light Healing up to Greater Healing, Refreshment, Mana, Antidote, Cure Blindness, Night Vision, See Invisible, True Sight, Flying, Haste, Sanctuary, Fire Shield and more. Pick one in the Professions window and press Mix, or type mix light healing.
Each skill goes from 0 to 300 in six tiers. A herb or potion near your skill teaches you most; easy ones teach nothing. Higher tiers climb more slowly. While it still teaches you, each one also gives a little experience.
Herbs stack: however many you carry, they take one place in your inventory.
Once a herb is gathered, its line ("Pale dewpetal flowers grow here.") disappears from your log, and from the log of everyone else in the room.
