Currently not farming any tomes as I finished gearing my alt jobs and main, for a few weeks now. I just do Mentor, Normal, and Trial rous when I log in during the morning. Also, I haven't done AR or MSQ for years unless it's for an event, since it's too boring.

I'm not sure if there's anything to buy with helios apart from selling the crafting mats. If you want to boost ilvl you can run the 2nd tier of normal raids, as they unlocked it a few days ago, and it gave out i740 gears.
