Now that Celestial Boost cost is tied to its level.
It is now much affordable at low level. For example I have it at lv9 and the cost of activate it for 7d is 130 gems. If I purchase the daily gem pack I can maintain the boosts 24/7 and still have gems to upgrade other stuff.
The question is: Should I level up my Prestige Level? Some of the boosts are good at lv9 only (-15% food cost…) and those at lv 11-14 are not really tempting.
Please share your prestige level and gem cost to activate it for 7d. This could be a good source for the wikia team.
