The Miracle Chest is a diamond-funded draw with a chest tier bolted on top, and a shop selling the keys that open the chests. It runs for a week.
The one rule that costs people rewards: you can hold four unopened chests. While you are holding four, summons stop giving you chests at all. Open something before you keep pulling.
How it works
Summons cost diamonds: 100 for one, 500 for five. One summon a day is free.
Every summon gives you an item from the guaranteed table. On top of that, roughly a quarter of summons also drop a Miracle Chest, which sits in one of your four slots until you spend keys to open it.
The picture at the top of this page is that row of four: the number under each chest is what it costs in keys, against how many you are holding.
Both halves earn points, and points unlock the milestone track:
- a summon is worth 10 points
- every key you spend is worth 5 points
What a summon actually gives you
Every draw returns exactly one of these:
| Item | Amount | Chance |
|---|---|---|
| Chest | 1 | 33.71% |
| EXP | 60 | 22.47% |
| 5m speedups | 15 | 22.47% |
| Diamonds | 10 | 11.24% |
| Green resource chest | 3 | 5.62% |
| Gold puzzle piece | 1 | 4.49% |
Those six add up to exactly 100%, so that is the whole table.
The chests, and what they are worth
Five tiers exist. The drop rate is the chance that a single summon also drops that chest:
| Chest | Drop rate |
|---|---|
| Advanced | 7.50% |
| Excellent | 6.20% |
| Fine | 5.30% |
| Legendary | 3.10% |
| Common | 3.00% |
Added together that is 25.1%, about one summon in four coming with a chest of some kind. Legendary is the rare one, at roughly one summon in thirty-two.
Opening any chest has a 5% chance to double whatever it gives you.
Higher tiers cost more keys and pay more, but the shape of the payout is the same: each tier's table is built from the same rewards in different sizes. A Legendary chest pays out on a sixteen-entry table whose two largest single outcomes are 5,000 speedup material and 3,750 five-minute speedups, at 10.86% each.
The key packs
This is the part of the event that is a shop. Four packs, each buyable with Red Diamonds or with money, each capped at a handful of purchases.
| Pack | Keys | Diamonds | Red Diamonds | Price (CAD) |
|---|---|---|---|---|
| Superior | 50 | 1,000 | 100 | $14.99 |
| Advanced | 100 | 2,000 | 200 | $29.99 |
| Epic | 250 | 5,000 | 500 | $74.99 |
| Mythic | 500 | 10,000 | 1,000 | $149.99 |
Red Diamonds themselves come from the game's own Top-Up Center, which is where the money side of all four of these actually starts.
They scale perfectly linearly. Every pack is 3.33 keys per dollar, 66.7 diamonds per dollar, and exactly two Red Diamonds per key. There is no bulk discount at any tier.
What actually differs is the chest thrown in: Superior includes a Fine chest, Advanced an Advanced one, Epic an Excellent one, and Mythic a Legendary one. If a bigger pack is worth more to you than several smaller ones, that included chest is the entire reason.
The milestone track
Points accumulate across the whole event and unlock six rewards, at 100, 500, 1,000, 2,000, 5,000 and 10,000.
The first four arrive quickly. The last two do not: at 10 points a summon, reaching 10,000 points on summons alone would take 1,000 summons and 100,000 diamonds. Keys close some of that gap at 5 points each, which is what the top of the track is really asking you to buy.
