EXP/Evolution/Skill Boosters

EXP Booster maximizes the level of a selected hero to your current team level. The maximum team and hero level is 120.

If the hero's level is higher than one, or you have not maxed out your team level yet, you get back some Global Championship trophies in your Inventory. The formula for the number of trophies returned:

• (1,500 / 2,948,945) × (2,948,945 – (X–Y)) = the number of trophies that you will get.
  • 1,500 Global Championship trophies are the price of the booster.
  • 2,948,945 is the amount of EXP the booster uses. It is also the maximum number of EXP a hero can have.
  • X is the maximum EXP points a hero can have on the highest reachable level.
  • Y is the EXP points a hero currently has.

Example

Let's say your Galahad is at level 30 and currently has 6,675 EXP. Also, your team level is 60, so you can upgrade Galahad up to level 60 by using an EXP Booster. At level 60, Galahad can have a maximum of 174,094 EXP points. Let's insert these numbers in the formula:

X = 174,094;

Y = 6,675.

Then, we can calculate:

• (1,500 / 2,948,945) × (2,948,945 – (174,094 – 6,675)) = ~0,0005087 × (2,948,945 – 167,419) = ~0,0005087 × 2,781,526 = 1,414.

So in this case, you will get 1,414 trophies in return.

Evolution Booster increases the evolution level of a selected hero by one star. You cannot raise your evolution level beyond the Absolute Star.

If you already have Soul Stones of the chosen hero and the evolution requires fewer than 300 Soul Stones, you get back some Global Championship trophies in your Inventory. The formula for the number of trophies returned:

• (1,500 / 300) × (300 – (X–Y)) = the number of trophies that you will get.
  • 1,500 Global Championship trophies are the price of the booster.
  • 300 is the number of Soul Stones the booster uses.
  • X is the number of Soul Stones required to evolve a hero to the next star.
  • Y is the number of Soul Stones you already have for this hero.

Example

Let's say you want to evolve Galahad from the fourth to the fifth star. You already have 25 Galahad's Soul Stones, and you need 150 overall. Let's insert these numbers in the formula:

X = 150;

Y = 25.

Then, we can calculate:

• (1,500 / 300) × (300 – (150 – 25)) = 5 × (300 – 125) = 5 × 175 = 875

So in this case, you will get 875 trophies in return.

Skill Booster upgrades the skills of a selected hero to their current level. The maximum level of the first and second skills is 120, the third skill is 100, and the fourth is 80.

If you have already upgraded some skills of the chosen hero, you will get back some Global Championship trophies in your Inventory. The formula for the number of trophies returned:

• (1,500 / 20,032,100) × (20,032,100 – (X–Y)) = the number of trophies that you will get.
  • 1,500 Global Championship trophies are the price of the booster.
  • 20,032,100 is the amount of gold the booster uses. It is also the total number of gold required to upgrade all skills of a hero to the max level.
  • X is the gold required to upgrade skills to the hero's current level.
  • Y is the gold you have already spent on upgrading the hero's skills.

Example

Let's say your Galahad is at level 6. He has the first and the second skills unlocked, and you have already spent 200 gold on upgrading these skills. To upgrade the first and the second skills to the sixth level, you need 10,000 gold. Let's insert these numbers in the formula:

X = 10,000;

Y = 200.

Then, we can calculate:

• (1,500 / 20,032,100) × (20,032,100 – (10,000 – 200)) = ~0,00007487 × (20,032,100 – 9,800) = ~0,00007487 × 20,022,300 = 1,499

So in this case, you will get 1,499 trophies in return.
