Based on player feedback, we have made improvements to the Champion and Grand Champion Packs to increase their overall value!
Grand Champion Packs have been reduced in price to just 260 Gems, while the Champion Packs have been reduced in price to just 30 Gems. Additionally, within both packs, the odds of 2* and 3* Heroes have been significantly increased, so you have much better chances at pulling these higher value heroes.
All guarantees remain in place on these packs, with counters continuing from prior to the price change.
These changes take effect beginning with the weekly pack release on May 4, 2017 at 2:00 PM PDT.
