The key is in the stone

FUZZY!
A new event begins in Sphere 3, in which you can get one of four unique epic amulets, as well as many useful consumables!
 
Mysterious keys are hidden all over the world, enclosed in magic stones. It's not difficult to find them, it's enough just to fight monsters or complete daily tasks that can be obtained in Greenwald and the Crow Legion Camp.
 
When extracting magic keys, you will be able to get enchantment scrolls, potions and much more. And when combining Great Magic Stones, you have a chance to get a Mysterious Hiding Place, as well as the "Mysterious Key Power" effect. The effect is summed up to 40 times, its maximum leveling gives an additional 20% of health and experience and 16% of protection.
 
The mysterious cache contains one of four amulets:

• Talisman of Keys — increases the power of abilities by 3%.
  
• Talisman of Secrets — reduces the cost of abilities by 3%
  
• Talisman of Life — increases health regeneration by 20%
  
• Shroud Talisman — reduces damage received by 2.5%
  

If you haven't received a Mysterious Cache in 24 attempts, you are guaranteed to receive it on the 25th attempt!
 
While the Premium account is active, the chance of dropping magic stones doubles.
 
Additional stones can be purchased at the store.
 
Good luck with your adventures!
