question about unlocking job

[tranquilla]

So Niwashi and Rongway did a great job explaining how to turn your class(Lancer) into a job(Dragoon). If thats what you were asking, ignore me. But your post was a little unclear, so ill answer a separate question to cover all bases.

Were you trying to figure out how to unlock other classes on your character? Like if you started as a Lancer and wanted to try out being a Gladiator instead?

So, the most basic requirement to unlock other classes is to level your first class up to 10. You also need to do the first few class quests, also up to level 10. When you finish that quest the guildmaster will give you permission to explore other classes, which unlocks the Armory system that lets you switch. Level 10 plus the quest gets you all the ARR classes(LNC, ARC, CNJ, ROG, MRD, ACN, THM, PUG, GLD) plus all the crafter and gatherer classes(MIN, BTN, FSH, ARM, BSM, CUL, CRP, LTW, ALC, GSM, WVR). If you want the Heavensward jobs(DRK, AST, MCH) you need to do the previous requirement, plus follow the storyline until it sends you to Ishgard(where the job trainers are) - along with buying the expansion. For the Stormblood jobs(SAM, RDM) you need a combat class at level 50 along with the previous requirement(the level 10 quests) - and again, having bought the expansion. The initial trainers for these two are located in Ul'Dah.

Thank you for answer , what i wanted to know was about how to unlock the job of certain class by hitting the level 15 from other one for excample; unlocking the black mage after becoming lvl 15 in archer.
