Transformation Planes are the continuation of the plot line after Main Chapter 7.2.
After Chapter 7.2, you can look forward to amazing adventures in June's, Itu's, and Marcus's planes, followed by the Epilogue. Each of these planes is unique, varied, and interesting in its own way.
In these Transformation Planes, the cards gained from all the rewards will be given to all three factions regardless of the faction you chose in the game's lobby.
The equipment card frames vary in appearance in each plane. When you receive an equipment card in June's plane, a blue triangle will be displayed at the top of this card. This indicates that you received this equipment card in June's plane.
Equipment cards obtained in Itu's plane feature a red rhombus, those from Marcus's plane have a purple pentagon, and ones from the Epilogue have a golden hexagon.
All cards, as well as collected sets, that you reacquire in each of the Transformation Planes will give you an additional reward: STABILITY.

IMPORTANT! When you receive equipment cards in the Transformation Planes, you have the opportunity to upgrade these cards using shadow energy. In other words, if you are unable to upgrade a card with the help of shadow energy, you first need to get this card in the current world, and then you can use shadow energy to upgrade it.
