A free player's steady diamonds come from daily and weekly quests (1,500 a week), the Arena of Heroes (36 to 80 a day plus a season reward) and Hunting Fields Contract (100 per finished challenge, with attempts that refresh twice a day). On top of that sit large one-time pots: 41,200 from chapter grand prizes, 23,877 from the Peaks of Time and 8,900 from player levels. The best places to spend them are the cheap early Fast Rewards each day and Tavern summons in batches of ten.
Steady income
| Source | Diamonds | How often |
|---|---|---|
| Daily quest chest (80 activity points) | 100 | Daily |
| Weekly quest chests (80 and 150 points) | 300 + 500 | Weekly |
| Arena of Heroes daily reward | 36 (below rank 300) to 80 (rank 1) | Daily |
| Arena of Heroes season reward | 360 to 800 by rank | End of each season |
| Hunting Fields Contract personal reward | 100 | Each finished challenge |
| Monthly Card (paid) | 100 | Daily for 30 days |
Daily quests hand out 160 activity points if you do every one, so reaching 80 for the diamond chest only takes half of them. The weekly list offers 230 points against the 150 needed for the 500-diamond chest.
Arena diamonds by rank on a single-server Arena (grouped-server Arenas pay more: 42 to 96 a day and 420 to 960 a season):
| Rank | Daily | Season |
|---|---|---|
| 1 | 80 | 800 |
| 2 | 75 | 750 |
| 3 | 70 | 700 |
| 4 to 10 | 68 down to 56 | 680 down to 560 |
| 11 to 20 | 54 | 540 |
| 21 to 40 | 52 to 50 | 520 to 500 |
| 41 to 100 | 48 to 45 | 480 to 450 |
| 101 to 200 | 42 to 40 | 420 to 400 |
| 201 to 300 | 38 | 380 |
| Below 300 | 36 | 360 |
One-time diamonds
| Source | Diamonds |

| Peaks of Time | 23,877 across all 56 realms |
| Player levels | 10 per level up (4,000 to level 400), plus 100 to 300 at every 10th level to 200 (4,900) |

Most of the Peaks of Time total, 19,477, sits in the second chain of realms (The Depths of Time onward), with 5,000 in Gold Rush alone. The full breakdown is in the Peaks of Time guide.
What diamonds cost
Most diamond costs in the game are fixed. Fast Rewards, Store refreshes, hero slots and Resonating Crystal slots get more expensive with each purchase.
| Purchase | Diamond cost |
|---|---|
| Tavern summon (all heroes) | 300 for one, 2,700 for ten |
| Stargazer | 500 for one, 5,000 for ten |
| Draconis Faction Pack | 500 for one, 5,000 for ten |
| Hero Choice Pack (VIP 15 and up) | 300 for one, 3,000 for ten |
| Bounty Board refresh | 50 |
| Change Tavern faction pool | 300 |
| Store or Guild Store refresh | 100, 100, 200, 200, 400, 400, 600, 600, 800, 800, then 1,000 to 2,000 |
| Barracks or Labyrinth Store refresh | 1,000 each |
| 5 extra hero slots | 100, 100, 150, 150, 200, 200, then 300 per purchase |
| Resonating Crystal slot (diamond unlock) | 800 for the first two, 1,200 up to the 6th, 1,600 to the 10th, 2,400 to the 15th, 4,000 to the 20th, 6,400 after |
| Rename | 500 |
| Create a guild | 500 |
The Tavern's single summon costs 300 but ten cost 2,700, so a single pull is 11% more expensive per hero. Save diamonds until you can afford ten. Stargazer and Draconis draws cost the same per pull either way.
Fast Rewards
Each Fast Rewards use gives 2 hours of AFK rewards. The first each day is free and the price then climbs:
| Use of the day | 1st | 2nd | 3rd | 4th | 5th | 6th | 7th | 8th | 9th | 10th to 20th |
|---|---|---|---|---|---|---|---|---|---|---|
| Diamonds | 0 | 50 | 80 | 100 | 100 | 200 | 300 | 400 | 600 | 800 |
How many uses you get a day, the free one included, depends on VIP (1 at VIP 0, 5 at VIP 6, 7 at VIP 9, 20 at VIP 18). Uses 2 to 5 cost 330 diamonds together for 8 hours of rewards; use 10 alone costs 800 for 2 hours. After the 5th use the price doubles to 200 and keeps climbing, so the 2nd to 5th uses are the efficient ones.
The Store
The Store sells for gold and diamonds and gets better as you push the campaign. Its diamond goods, aside from gear chests that change with your stage:
| Item | From stage | The game's diamond value |
|---|---|---|
| Arcane Staff | Start | 300 |
| Time Emblem | Start | 500 |
| 10 Elemental Cores | Start | 200 (20 each) |
| 8 Bait | Start | 320 (40 each) |
| 200 Poe Coins (400 from 28-1) | 18-1 | 1 per coin |
| Mythic Variety Chest (any non-Dimensional, non-Draconis Mythic gear) | 20-1, 90% price; 80% from 30-1 | 6,000 |
| 3 Large Hero's Essence Chests | 29-1 | - |
For gold it sells Hero's Essence (up to 500 at a time from 10-22), 20 Elemental Shards (from 22-1), 10 or 20 Primordial Emblems (from 18-1 and 20-1) and Poe Coins.
Several diamond slots carry a standing discount that deepens with progress: three gear-chest slots sell at 90% of list price at the start and 60% from 10-22, and the Mythic Variety Chest drops to 80% at 30-1. A refresh costs as much as some items, so look at the discounts before paying for one.
Buying diamonds
Each regular diamond pack can be bought any number of times. Each size also has a first-purchase version that doubles the diamonds, once.
| Price (US) | Regular pack | First purchase |
|---|---|---|
| $4.99 | 300 | 600 |
| $9.99 | 780 | 1,360 |
| $19.99 | 1,480 | 2,560 |
| $29.99 | 2,380 | 3,960 |
| $49.99 | 4,030 | 6,560 |
| $99.99 | 8,480 | 12,960 |
The cards are far better value than any pack. The $4.99 Monthly Card gives 300 diamonds on purchase and 100 a day, 3,300 in all, eleven times the regular $4.99 pack. The $14.99 Deluxe Monthly Card gives 980 diamonds on purchase and a daily choice chest that includes 600 diamonds, 18,980 over 30 days if you take the diamonds every day. Both also count toward VIP. The VIP guide covers the cards' extra daily chests.
Best ways to spend
Put diamonds where the price per use is lowest and the item would otherwise be hard to get:
1. Fast Rewards uses 2 to 5 every day (330 diamonds for 8 hours of AFK rewards).
2. Tavern summons in tens (270 diamonds a hero instead of 300).
3. Discounted Store slots, the Mythic Variety Chest in particular once it reaches 80% at 30-1.
4. Honorable enrollment in the Abyssal Expedition if you reliably reach Prince, which turns 3,000 diamonds into 6,000.
Leave the late Fast Rewards (800 each) and deep Store refreshes (1,000 and up) for when you have a specific reason. A Faction Hero Scroll is valued at 480 diamonds and a Common Hero Scroll at 270, which is a handy yardstick when an event offers to trade diamonds for scrolls.
