Starting from League 10 you can get Legendary Chests. It takes 36h [24h] to unlock a Legendary Chest without using the "Time Loop" Guild bonus. The number of cards and amount of gold inside a Legendary Chest depends on the league level at which you got it. Some quests in Events require you to open Epic Chests in Event shop.
Speeding up chests Edit
Legendary Chests can be opened immediately by paying gems. This speedup makes you spend 0.125 gems per every minute remaining, increasing first to 0.183 gems per every minute remaining once the timer goes below 6h, and further to about 0.317 gems for every minute remaining once the timer goes below 1h.
More precisely, we have:
- time < 1h: cost = 19 gems/h = 0.317 gems/min; time spared = 3min 9.5s/gem
- 1h < time < 6h: cost = 11 gems/h = 0.183 gems/min; time spared = 5.5 min/gem
- time > 6h: cost = 7.5 gems/h = 0.125 gems/min; time spared = 8 min/gem
This means it costs 11 gems for a 1h 1s speedup, but 19 gems for a 59min 59s speedup; and 45 gems for a 6h 1s speedup, but 66 gems for a 5h 59min 59s speedup.
