Hero Wars is a mobile free-to-play game available on Google Play and Apple App Store. Although the game is free to play, some of the items might be purchased. Some in-game mechanics can be obtained in a random matter. This article is aimed to present the odds of game mechanics involving randomized drop.

This article covers the following game mechanics:

• Circle of Summoning - a mechanic available on the guild screen. Circle of Summoning contains Titan fragments.
• Artifact Chest - a chest available in the Airship on the main screen. Artifact Chest contains Artifacts and artifact-related items.
• Outland Chest - a chest available in the Outland section after defeating one of the Outland Masters. Outland Chests contains Outland Coins and Skin Stones.

• Altar of elements - a mechanic related to the guild boss fights.

Probabilities for first opening:

New titan drop chance is 50%.

• Hyperion, Araji, Eden drop rates are increased with every new Sphere opening
• New titan chance changes with every new titan collected
• Keros, Amon, and Iyari are unavailable during the first summoning, but for subsequent sphere openings, their drop rates will follow the normal rules

• 3 titans with the most fragments (no matter evolved or not) are weighed as 1000000 amount of soul stones ^1.5
• the calculated weights are used to receive a probability
• this probability is used to determine which titans’s fragment is to be dropped next
• the exact amount of fragments to be dropped is calculated with the following chances

Drop rates (%) for different entities, depending on the chest level:

amount of chaos cores by chest level:

Artifact fragments amount by chest level:

Chances to get specific artifact types:

amount of artifact coins amount varies regardles of chest level:

amount of white resources varies regardles of chest level:

amount of green resources amount varies regardles of chest level:

amount of blue, purple and orange resources amount varies regardles of chest level:

The first Grand Prize has a 25% chance of drop. All subsequent Grand Prizes have a 0.5% chance of drop. Grand Prize’s chances are calculated before regular rewards.

All the rewards that can be received from Tower Chests are shown in the Tower Chest open window. Chances for those rewards do not change and remain as follows:

• Start time: 2023-11-17 02:00:00 UTC+0
• End time: 2023-11-21 02:00:00 UTC+0

• Each lot containing a Talisman can only be received once (if the player already has a Talisman, they cannot receive the lot containing that Talisman).
• Lots that do not contain a Talisman can drop any number of times.
• Below there is the formula that determines the lot drop chance based on which Talismans the player owns.
• When opening ten (x10) Reward Boxes in one click, the chance calculation is no different to opening one (x1). The boxes are opened one by one, and the chance is recalculated for each subsequent box.

• X is the drop weight for the lot that the drop chance is being calculated for.
• SUM is the sum drop weight for all lots that match the Drop Condition for the player at the moment of opening.
• Example
  • Situation 1: The player has no Talismans, so all of the drop conditions from the table below are met (i.e. the player can receive any of the 25 lots). To calculate the chance of lot #10 dropping (which contains a Talisman of Direction), the values for the formula above are:
    • X = 40 (drop weight for lot #10 from the table below)
    • SUM = 1631
      • The calculation is: SUM = 40 * 12 (drop weights of the first 12 lots = 40) + 10 * 2 (drop weights for lots #13 and #14) + 1 * 6 (weights for lots #15, #16, #17, #18, #19, #20) + 225 * 5 (weights for lots #20, #21, #22, #23, #24, #25)
    • Drop chance = 40 / 1631 = 2.45% (rounded)
  • Situation 2: The player has a Talisman of Vengeance and a Talisman of Concealment, so the drop conditions from the table below are not met for lots #13 and #14 (the player cannot receive lots #13 or #14). To calculate the chance of lot #21 dropping, the values for the formula above are:
    • X = 225 (drop weight for lot #21 from the table below)
    • SUM = 1611
      • The calculation is: SUM = 40 * 12 (drop weights of the first 12 lots = 40) + 1 * 6 (drop weights for lots #15, #16, #17, #18, #19, #20) + 225 * 5 (weights for lots #20, #21, #22, #23, #24, #25)
    • Drop chance = 225 / 1611 = 13.97% (rounded)
