Get Space-Time Coins From the Cave of Space-Time

Space-Time Coins are a special currency in MementoMori. They are gained by clearing the Cave of Space-Time trial. Consistently clearing the Cave of Space-Time every time it refreshes (once every 48 hours) will get you these coins, which you can then use to buy items at the Space-Time Coins shop.

How to Clear the Cave of Space-Time Trial

Get More With Each Run

To maximize your Space-Time Coins in every run, try clearing the third stage on hard mode. Some path options also grant you a couple of thousands more Space-Time coins, so make sure you check how much you'll be earning for each battle.

Treasure Ship of Dark Illusions

At the Level 3 Hard mode, you get to fight encounters like the Treasure Ship of Dark Illusions. This encounter grant large amounts of either Guild Coins, Battle Coins, or Space-Time Coins. These rewards are the best out of any of the other encounters, so try not to pass up on them. Note that you can only challenge this once, so make sure the enemy you're facing isn't too far out of your league. You only get one of the rewards in this encounter, so do your Cave of Space-Time as frequent as possible.

Use Space-Time Coins To Buy Character Copies and Shards at the Shop

We recommend using Space-Time Coins to buy copies of the characters you need. Powerful and useful characters like Cordie, Merlyn, and Amleth are available here for 120,000 Space-Time Coins, which you can gain fairly quickly depending on how consistent you are with clearing the Cave of Space-Time.

The Space-Time Coins shop is a good source of character copies, so make sure to keep clearing the Cave of Space-Time for fast progression through MementoMori.

Character Shards	Priority Purchase
Cordie	★★★★★
Merlyn	★★★★
Amleth	★★★
Fenrir	★★★
Amour	★★
Hathor	★★
Tropon	★★
Freesia	★
