Diamonds are the prime currency of MementoMori, as it allows players to pull the characters they want from the game's gacha banners. Read on to learn how many free diamonds players can get per day and per month.

Daily Diamond Income

Minimum and Maximum Daily Diamond Income

Game Mode/Feature	Minimum Income	Estimated Maximum Income
Daily Missions	100	100
Cave of Space-Time	100	350
Fountain of Prayers	10	*800 (getting all UR Quests worth 100)
Battle League	25	**850
Guild Raid	10	560
Monthly Boost Premium Gift	150	150
Total	245/day 395/day	2660/day 2810/day

This list did not include weekly missions, main quest rewards, or Tower of Infinity's first clear diamonds. *Fountain of Prayers Normal Quest only.
**Highest Battle League Rank

If you are at Player Rank 110, Fountain Rank 4, Battle League Rank 450, and have a Monthly Boost subscription, this is what your daily Diamond Income may look like:

Game Mode/Feature	Estimated Income
Daily Mission	100
Cave of Space-Time	350
Fountain of Prayers	40
Battle League	130
Guild Raid	30
Monthly Boost Premium Gift	150
Total	850/day

This can go higher depending on how you do well in Battle League, when you level up your Fountain Rank to level 8, and when you have an active guild that does Guild Raid every day.

Daily Missions

Doing your daily missions can grant you 100 Diamonds from your 80th Contribution medal. Make sure to do your dailies to have diamonds, a supply of orbs, and sealed keys.

Daily Quests and Tasks Checklist

Cave of Space-Time

The Cave of Space-Time offers Cave Coins and Diamonds when you clear Levels 2 and 3. You will get 350 Diamonds every 48 hours (2 days) if you clear your Cave of Space-Time trial: 100 Diamonds when you clear level 2 and 250 Diamonds when you clear level 3.

How to Clear the Cave of Space-Time Trial

Fountain of Prayers

The Fountain of Prayers can give a maximum of 150 Diamonds per quest on its Normal Quest when you reach Fountain Rank 8. However, this is given out at random.

Usually, you can get 60-100 Diamonds from the Normal Quest and 120-200 Diamonds at the Team Quests.

You can reroll your Normal Quests to get your desired quests. We recommend rerolling your Normal dispatch to get Diamonds so that you can get the optimal number for the day. We have tried rerolling our Normal Quest for 6-7 times (120 - 140 Diamonds cost), and the return is around 520. You still get 400 more even with the reroll cost. Have a limit on your rerolls, however, to make sure you're getting more and not spending more.

Watch out for the Republic of Nedel quests on the Normal or Team Quests, as that is where you get your Diamond income from the Fountain of Prayers.

Normal Quest
Republic of Nedel	- LR Diamonds x 150 - UR Diamonds x 100 - SSR Diamonds x 60 - SR Diamonds x 40 - R Diamonds x 20 - N Diamonds x 10
Team Quest
Republic of Nedel	- LR Diamonds x 300 - UR Diamonds x 200 - SSR Diamonds x 120 - SR Diamonds x 80 - R Diamonds x 40 - N Diamonds x 20

Guild Raid also gives you Diamonds in the form of Diamond bags. You get 2 challenge attempts (3 if you have VIP 7) for both Sonya and Luke Guild Raids. Guild Raid events also give you 2 challenge attempts.

Ideally, you can get all three bags to get 140 Diamonds per Guild Raid which gives you a total of 560 Diamonds. However, depending on the damage dealt by the guild, players may get 1 or 2 bags per Raid, which often are Diamond Bag (S) and Diamond Bag (M) worth 10 and 30 Diamonds, respectively.

Diamond Bag (S) 10 Diamonds

Diamond Bag (M) 30 Diamonds

Diamond Bag (L) 100 Diamonds
