As part of the Part 1 Improv-Singularity Repair Support 3 update, there have been changes to the Prison Tower and Arjuna/Karna Trial Quests.
Both events no longer require Rare Prisms to purchase and instead just require completion of the Main Story. The Prison Tower requires London completed and Arjuna/Karna Trial Quest requires E Pluribus Unum completed. Any Rare Prisms used to purchase either event will be refunded.
There is also a second chance to get Dantes and Arjuna’s Costumes for players who have cleared London and E Pluribus Unum.
To commemorate this change, there are 2 Summoning Banners for both events.

Another new change in the update is the inclusion of “Pure Prisms”.
These Pure Prisms can be redeemed at the shop for materials and are intended to help Part 1 players gain access to materials that are locked behind Parts 1.5 and 2. 1 Pure Prism can be exchanged for Bronze materials, 2 for Silver, and 3 for Gold and there is a exchange limit of 100 of each material. Pure Prisms are given for clearing Main Quests and are retroactively given to all players. It looks like for players who are completely caught up there will be 1011 Pure Prisms.
Finally new permanent Tutorial Missions have been added to Master Missions that rewards players who have been leveling their Servants with even more Class materials to raise even more Servants.
