Oh and I think the wait at the Inn approach should potentially be revised somewhat now that League of Honor actually has something that is definitely worth farming.

League of Honor opens when you get 12 Heroes. It might be worth grabbing 1-2 Heroes from the store with Rubies if you really like those heroes and it would get you up to that 12 Heroes number.

League of Honor is currently the only place you can farm Unique Treasure (aside from getting lucky on Gacha) as a rate of 1 every 3 weeks. By buying heroes with rubies you're knocking off 18-21 days to you getting League of Honor access. So every Hero you buy with rubies is effectively gets you to LoH access 3 weeks earlier and so is worth ~1 Unique Treasure. I 100% would pay 4-6k Rubies (hero cost) to pick out a Unique Treasure of my choice.

Rubies are in game currency that can be earned. By the time you get access to the final chapter you'll likely have 15k+ Rubies (at least that's roughly what I had)
