| How to Reroll |

The first step to reroll is to sign in as a guest. When opening the game for the first time, it will ask you to sign it to Google Play.
Ignore this message and select “Close”. This way, the game will allow you to use a guest account that you can reroll with.

Next, you'll need to play through the tutorial until you reach Quest 2-1.
You can breeze through the quests by pouring all your leveling materials into Iris until Quest 1-9, then into Rosalie for the succeeding quests. Doing so will level them up to around Level 15 and Level 10 respectively.
This should be enough to defeat the tutorial boss Natasha. Otherwise, losing will only result to a short delay in your rerolling process, so don't worry!
List of All Quest Walkthroughs

After defeating the boss and Quest 2-1, the game will teach you how to pull characters from Invocation banners. This is where you will get your first out of three sets of 10-pulls, so watch out for who you get in this segment.
Finish the tutorial and Quest 2-2, then go back to the Home Screen where you can start claiming your rewards by going through the different menus. By the end of it, you will most likely get at least 20 Tickets of the Cursed and a copy of the limited SR unit Natasha, as well as a few hundred Diamonds.
Depending on when you signed up, you could end up with more Tickets of the Cursed or Diamonds overall.
List of All Invocation Banners (Gacha)

Pull from the Prayer of the Cursed banner with your 20 Tickets of the Cursed. Aim to get a strong DPS carry like Cordie or Florence, and a solid support unit like Merlyn.
You can then spend all the the Diamonds you have left on any of the Prayer of the Fleeting Banners, which are the game's limited gacha banners for limited SR rarity units.
If you didn't get your desired characters, you need to reset your game data and start the process all over again from the beginning.
| 1 | ![]() Go back to the Home tab and click on the hamburger icon on the top right corner of the screen. Then, select “Return to Title”. |
|---|---|
| 2 | ![]() Once you're on the title screen, select the cog icon in the top right corner. |
| 3 | ![]() Next, select “Reset Game Data” |
| 4 | ![]() Then, confirm that you'll reset your data. |
| 5 | ![]() Your game should restart by this point. Repeat steps 1 to 4. |

Once you have all your desired characters, go back to the Home Screen and select the hamburger icon on the top right corner of your screen. Then, select “Account Link”.
Here, you will link your reroll account to either a Google account of your choice or a password. This way, you will not lose your hard-earned units.
| Which Character Should You Reroll For? |
|---|
|
|
Cordie
・Great attacker with skills that buff her ATK straight-up without any turn requirements. ・Transitions into a good debuffer later in the main quest when you get her unique weapon, which can shave off 80% of the enemy's DEF. ・Easy to level up for F2P players because you can get copies of her from the shop with Space-Time coins. |
Florence
・Florence's value is in her increasing number of attacks the more critical hits she successfully does. This is why pairing her with Merlyn gives you one of the best attackers in the game for PvE. ・Has great CRIT and ATK self-buffs that are not dependent on how long she remains alive in battle. ・Useful for clearing most of the Main Quest, though tougher to Awaken because you can't buy copies of her from the Cave of Space-Time. |
We recommend aiming for powerful standard SR units such as Cordie or Florence who can dish out tons of damage and buff themselves.
Though the same in some aspects, Florence will have an easier time clearing the beginning of the game compared to Cordie because of her high hit count.
Cordie, on the other hand, is a lot easier to level up compared to Florence because you can buy copies of her through the Space-Time shop.
| Best Characters Tier List | |
|---|---|
| Best PvE Characters | Best PvP Characters |
Merlyn
・Merlyn's passive skill, Apprentice Wanted!, is a great buff for Attackers. ・She also has rudimentary healing abilities with Master and Apprentice, a useful skill to have in the early game. ・Like Cordie, Merlyn is also easy to level up because her shards can be bought from the Cave of Space-Time shop. If you clear the Cave of Space-Time consistently, you're guaranteed one copy of Merlyn per month. |
Primavera
・Has good ATK and SPD buffs for all party members, as well as debuff options in the form of preventing her enemies from getting their own buffs. These come at a relatively low investment cost. ・She can also inflict the Faint debuff on enemies, which opens them up to damage from your main Attackers. |
For support units, we recommend either Merlyn or Primavera.
Merlyn raises the CRIT rate of the witch next to her, so always keep her close to your DPS carries. Like Cordie, Merlyn is also easy to awaken because you can buy copies of her through the Space-Time shop.
Primavera, on the other hand, is fast and stuns enemies in front of her if her SPD is higher than theirs. She can also transition into a good offensive unit much later in the game.
| Time Consumed | Approx. Total: 8 - 10 mins. Account Creation: Less than 1 minute. Story Playthrough: 7 - 9 mins. |
|---|---|
| Number of Pulls After Clearing Quest 2-2 (No Additional Rewards) |
20 Tickets of the Cursed + 600~ Diamonds (equal to 2 Standard/Limited Pulls) |
| Pull Rate | Prayer of the Fleeting: • SR Standard Character: 0.1475% • SR Limited Character: 1.37% Prayer of the Cursed • SR Standard Character: 0.2130% |
Assuming that you skipped all the cutscenes and kept clicking through the dialogue, it can take you anywhere between 8 to 10 minutes to reroll for the characters you want.
Between the short reroll time and having 20-30 free pulls from the Prayer of the Cursed Banner, it is definitely worth rerolling in MementoMori since your early progress in-game can be dictated by how good of a DPS carry you have at the start.
If the standard SR character you pull isn't a good DPS carry, you can farm Space-Time coins from the Cave of Space-Time to buy units like Cordie and Merlyn.
You can also buy the 1st Purchase Bonus pack to get Amleth.
