Mint safe

Forge: luck, class odds and recipes

Support service

The forge melts two or more of your safes into a new eternal safe. The source safes stay yours — you spend only AMA2 and the safes' "freshness". The result is random: you pay for a chance to forge a rare Silver or Gold.

2+ of your safes stay yours, mint counter +1
Luck rarity × √power × freshness
Traits alloy, monolith, overheat
New safe class by odds, 8–22% of the parents weight

Price

Price = 0.3 × P0 × n / 2 × max(1, (average weight passed on / A0)0.75) × (1 − discount)
P0 is the start price of a fresh safe of the epoch, n the number of safes; when the parents are heavier than the start weight A0 on average, the price grows with what they pass on; the discount is 1.5% per account level, up to 30%

Epoch Ziton. The price for parents no heavier than the start weight; heavier parents cost more. Network gas in BNB is charged on top. The exact price for your safes is on the forge page.

Forge luck

Each safe contributes to luck:

contribution = rarity × √power × (1 − 0.15·mints)
rarity — middle of the class multiplier: Regular 1, Silver 1.2, Gold 2.5; power — weight ÷ epoch start weight (35 AM), from 0.25 to 2
Luck = Σcontributions / 2 × mix     chanceclass ∝ chancebase × rarityluck − 1
Two fresh Regular safes with the epoch start weight give luck 1 — the same odds as a normal purchase. The higher the luck, the faster the odds of the rarest classes grow.

Rarity genes

Then the parents genes add to the top class chance: the five strongest genes in full, the rest by half, with freshness, plus the account level (+0.1 p.p. a level, up to 2). At most 40 p.p.; the other classes shrink in proportion, the top class stays at most 85%. Two average Regular safes (gene 2.25) lift Gold from about 4% to 9%. The forge panel shows what the genes add.

What is born

Anew = Σ min(Aparent, 4·A0) × (1 − 0.15·mints) × max(rolls) × class multiplier
n − 1 rolls, each from 8% to 22%; the expected best roll = 0.08 + 0.14·(n−1)/n
  • Class and image — by the odds above.
  • Weight is inherited: the new safe gets 8–22% of the parents total weight. Each parent counts at most 4 start weights of the epoch and 15% less for every past mint: heavy fresh safes forge heavy ones.
  • More safes mean more total weight and more rolls (the best one counts). A light safe adds little weight but costs like any other: choose your safes wisely.
  • The weight is a surprise: the forge shows only the weight range, the exact weight appears after the mint.
  • Its own traits: the lighter the rolled weight within its range, the better the capacity, growth, gene and mint resource; 20% of capacity and growth comes from the parents.
  • Level 0, mints 0 — the new safe can be upgraded, modified and forged right away.

Rules

  • A safe can join the forge as many times as its mint resource allows (Regular 2–4, Silver 3–5, Gold 4–6); safe levels 5 and 10 open one more slot each.
  • Free (demo) safes can't be forged.
  • The new safe is eternal and is yours on BNB Smart Chain.
