Well, you actually just need to unlock the Armoury system, which is still level 10. Level 15 if you started as a non-Lominsan class due to story lock-outs (damnable airship pass). Pugilist will make it 'easier' later on if you don't mind waiting till level 15.

You can get to Limsa before level 15, by having someone physically take you there or joining an FC with a house in the Mist.
