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

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

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:

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.

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.

Fountain of Prayers

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

Usually, you can get 60 Diamonds from the Normal Quest and 120-200 Diamonds at the Team Quests. You can reroll your Normal Quests to get your desired quests, but that will cost 20 Diamonds per reroll.

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	- UR Diamonds x 200 - SSR Diamonds x 120 - SR Diamonds x 80 - R Diamonds x 40

Please note that the table for Team Quest is incomplete. We will update it as soon as information is available to us.
