The third collaboration with Fate/stay Night: Heaven’s Feel with GungHo’s Puzzle & Dragons will be running from 10:00 JST, 22 March until 9:59 JST, 5 April. New with this iteration is the Emiya & Rider combo unit, as well as some of the older collaboration characters getting new forms, and everyone from the collab gacha will get assisted evolutions. True Assassin will be a rare encounter in the collaboration dungeon, while the first time clear reward of the dungeon will provide Fujimura Taiga, for those who missed out on the earlier runs.
You can check out the Heaven’s Feel special collaboration website with Puzzle & Dragons here. There’ll be free gacha for a variety of the collaboration gacha with the typical purchasable sets you can get from the shop. Saber Alter and Illyasviel are the ones who acquire new evolutionary forms, while everyone else, including the latest Emiya & Rider unit, all have assist evolutions. You can find the full details about the stats and materials through the official website here. Additionally, some characters have also received changes to their skills, be it active, leader or assist evolution skills.
The global version should be able to expect this to arrive in the coming months as it has with the previous collabs.
