In order to receive the HLA qualification you must have at least 1 level 60+ job and at least level 30 Alchemy. Once you have these, talk to High Alchemist Paracelsus while on a 60+ job to begin the HLA quests. High Alchemist Paracelsus will ask you which HLA discipline you would like to undertake: Weapon, Armor, or Tool. Note: Once you decide a discipline you are stuck with this choice. You can also only complete the quest once to receive just one discipline and its respective title.
