Find a crate
Crates are all called "Waylaid Crate". Monsters around level 8–20 can drop them; they are not bound and can be traded. The name gives the tier and material, like this one: Waylaid Crate: Apprentice Herbs .
Crates come in 4 tiers: Apprentice from level 10, Journeyman from level 10, Expert from level 20, Artisan from level 35.
