Clash of Clans December Update: 6 Details for Players

Boost Reduced to 5 Gems

And in what's probably my favorite change so far, is a revamp of the boost. Users can spend 10 Gems to speed up spells, barracks to build troops, and healing times for King and Queen by 4x for 10 gems each. That's usually 40 gems, as I only speed up one barracks during a boosting session to earn money for upgrades.

After the update next week, the boost will be changed to cost only 5 gems, not 10. However, it will only be one hour long instead of two. While this isn't "better" or cheaper, most don't have two hours to spend sitting on the couch gaming. Spending half the money for a 1-hour session makes more sense, and will likely result in a lot more users boosting.
