SAM Job Quests Too Overtuned

[Bourne_Endeavor]

I wasn't aware that there was gear that much higher, I've just been using the gear from quests. How do I acquire better gear?

Go to Idllyshire and talk with Hismena. She sells i260 Shire gear, which you can subsequently upgrade to i270 by purchasing Illuminati Deepest/Tautest/Darkest items. i270 will carry you to level 63-64, but I do advise upgrading before you reach the level 65 dungeon as stuff has much higher HP around this point.
