Challenges is a special game mode that rewards Challenge Points, which when reaching certain numbers reward Challenge Milestones and extra damage. It is unlocked at level 15. Every challenge has a set of Creatures with increasing levels. When the final creature of the challenge is defeated, the player is rewarded with extra damage, and other miscellaneous currencies. Rewards are given only one time per difficulty tier. There are two types of Challenges: Normal Challenges and Series Challenges.

Normal ChallengesEdit

In Normal Challenges, every Creature is labelled as a Boss, and the HP will be calculated as one. Completing a challenge for the first time rewards Challenge Points, Gold, AP, and Diamonds.

Note* Challenge Points, AP, and Diamond rewards remain constant regardless of mode or difficulty, but the Gold rewards only remain constant regardless of mode.

Currently there are 9 Normal Challenges. Completing every challenge on every mode on every difficulty yields:

  • 422.24M Gold
  • 3,385 Challenges
  • 5,950 AP
  • 11,385 Diamond.

Gold RewardsEdit

  • Gold reward for a specific challenge and difficulty tier is given by BGR \cdot D^2, where BGR = base gold reward for the challenge at Bronze I and D = difficulty rating.
  • Difficulty ratings range from 1 (Bronze I) to 5 (Bronze V), 6 (Silver I) to 10 (Silver V), and 11 (Gold I) to 15 (Gold V) for the purposes of the above formula.
  • Certain gold rewards are affected by a negligible rounding error. These are shown in brackets.

Difficulties and ModesEdit

ChallengeDifficulty

There are 3 Challenge difficulties: Bronze, Silver, Gold, each containing 5 difficulty tiers (I, II, III, IV, and V) within themselves. Each Tier and Difficulty will be blocked for each challenge until the player finishes the previous Tier.

Also, there are 3 Challenge modes:

ChallengeMode
  • Solo: The player goes alone against the Creatures;
  • Duo: The Challenge is fought in a two member party. If the player is in a party fighting in any of the common worlds, the game will try to enter the challenge with that partner;
  • Group: A group of 6 players fights the Challenge.

How to enter a ChallengeEdit

To enter a Challenge, the player must open the Game tab and select the Challenges icon. Then, he must choose the difficulty, mode, and Challenge. If Duo or Group mode is chosen, the player will enter a Challenge Queue, waiting for more players to join. It is also possible to check the open queues, joining other player's challenge. When setting up a Challenge, is possible to set a minimum level or an access password. The player can click the Start Now button to begin a challenge with fewer than the maximum number of players.

Challenges marked with a blue background have an access password. The Check green check indicates a challenge that you already completed.

Challenge Final Boss DamageEdit

Creatures in challenges undergo a constant level pattern. If x represents the level of the first monster in a particular Challenge, each successive monster in the Challenge will be x/5 levels stronger than the preceding monster. This is equal to Level = x \cdot (1+(0.2(Stage-1))).

In the following below tables the HP of the final bosses is shown without the HP reduction (Hunting Upgrades) effect. If needed look at the HP reduction table. The HP of the tables were calculated by the formula: HP = 4 \cdot ((LVL)^2 + 5)

The series challenge keeps track of how many stages the player has completed, rewarding 1 Challenge Point Challengesevery stage. Every 10 stages completed rewards 1% bonus damage, and every 50 stages completed rewards 5% bonus damage. The % bonuses within Series stack; total damage bonus from the challenge can be seen under the Series tab of the Challenge screen. Once all 170 stages have been completed, the player will be put to the next tier and set to the first stage at difficulty level 171.

The difficulty rating is given by D = (170 \cdot Tier) + Stage

The levels of the monsters in the infinite challenge is given by:  L = D \cdot (D+1)

Both the Series total percentage bonus and Challenge Point Milestones bonus are added together.
