Much like the pack that can be bought for the guild events, that gives a little discount. The pack gives unlimited of torches in the event. Can cost around 1200 gems.
This means people can do all Underspire rooms and finish it off whenever they like to.
Such a great request that I hope will come true.
You have to spend 300 gems per day, which is 2,100 gems minimum per week. A realistic price for unlimited Underspire moves would have to be higher than that - closer to 3,000 gems.
In my experience, I usually have only 1–2 Underspires YEARLY where I can’t clear all rooms using just the weekly torches. Most of the time I need around 4–5 x3 torch packs, and on the remaining days either zero or at most 1–2 packs. Overall, your option would result in an even higher gem loss.
Unlimited Torches for the Underspire as a VIP Level reward sounds pretty nice. Like a VIP 7-9 kind of thing 
Hell yeah!
it’s 2-3 actually. We have about 150 rooms, some of them are free, some unnecessary, some gives you torches back. So it’s the best decision to bye 3 packs for a 3 days then 2 packs for 2 or 3 days and then you’ll understand an amount needed by the sunday
You actually don’t have to spend 300 gems a day to get to Diamontina. You need to spend 150 gems Monday through Saturday (900 gems total) and none on Sunday. On Sunday you can use your 7 free to clean up the sentinel rooms. You can also spend 300 gems Monday-Friday (1500 gems) and get to Diamontina on Friday and then spend 50 gems Saturday and Sunday to get a full clear (1600 gems total). If your spending 2100 gems you will have torches left over, but they don’t transfer to the next week, so I don’t recommend it. I was doing the 150 gems/day and clean up Friday every week since Underspire came out. Since the update for Underspire I’ve been spending the 300 gems Monday-Friday and doing sentinel battles on Saturday (50 gems) and finishing my clean sweep of Underspire on Sunday, I like finishing all the battles for the experience.
Wouldn’t that cost more than doing 300 Monday-Wednesday and 150 Thursday-Sunday, with the same amount of torches? 1500 Gems total instead of 1600, because you’re spending 100 for an extra pack on Saturday and Sunday, rather than 150 for an extra pack on Thursday and Friday. Right?
I mean, it’s not a huge difference, but over many weeks that’ll add up and cost you a fortune in wasted gems.
Yas, every little helps.
I usually spend 800 - 1000 gems each week, depending on how lucky I get. That’s just for collecting all boss rewards plus most of the special loot within reach. Not sure if I would switch to visiting all rooms for 1200 gems, it’s extra effort for mostly useless rewards (hello traitstones, trinkets and extra single torches that just cover the room cost).
I don’t mind dragons either. I used to farm golden orbs for medals and sentinels; those goals are done. Now Underspire is mainly about visiting every room for a chance at deed books from the new treasure rooms. Gems themselves are mostly irrelevant at late game.
And simply put, the math doesn’t work out. Buying torches manually is still more efficient than the unlimited pack. Situations where (7 + 15) x7 torches aren’t enough are very rare, and they don’t justify paying an extra ~1k gems.
