Success Rate Increment System

Burn GMT to permanently increase following success rate (the improved % can be seen):
  1. 1.
    Improve 1% success rate of ALL Gem upgrade;
  2. 2.
    Improve 1% success rate to receive a higher quality Sneaker from opening Shoebox;
  3. 3.
    Improve 5% success rate to receive DOUBLE Sneakers from Shoe-Minting.
User can burn GMT for each category at max 5 times, and every time the cost will get more expensive.
If the original chance of Level 1 -> 2 Gem upgrade is 35%, improve 5 times will bring the success rate to 40% and adding a 25% chance on top of the original chance of receiving DOUBLE mint from Shoe-Minting.
