Level UP the Legion

Hi guys i am trying to find a easy way to level UP the legion so i can have the legion bank anyone knows?? if i am not wrong i need level 3 to get the bank

Yes you can have legion bank but i am not sure which lvl or how to get it.

Ya its level 3 but i just dont know what item to use to level UP maybe i just need to keep using that item on the girls inside legion ..

hello, in order to lvl up faster, all your guild member needs to work together and give the 4 little girls the items from instance.
also for you to know the requirement, you need to go to the lady NPC onside base(next to the guy that gives the key to open the capsule(little bag). she will tell you how much you need to do the quest which I call picking quest. when your legion succeed on that quest, the legion lvl right away.
Ps: sorry I don't upload any pictures but I hope you understand which npc I was talking about. any question just post it and as soon as I can I will replay you ^ ^
