Wizardry Variants Daphne question

I would like to ask for some information about the new gacha Wizardry Variants Daphne, releasing on October 15th:

• Has anyone tried it and can give me feedback on the gameplay modes and the playable characters?
• How many character and equipment rarities are there? How many playable characters are available?
• Do we know any of these characters and their abilities?

In terms of rerolling, it would be helpful to have this information to organize things better, but there’s very little information available online.

Thanks a lot to anyone who can respond!
