This is kinda complicated lol

There's a user on YouTube who posts strategy guides for Seven Knights Revolution. They cover common mistakes beginners make, essential characters for raids, rare cards or pets that are crucial to level up, efficient growth methods, how to use rubies, and much more, so I highly recommend checking them out. In-game, when you enter raids, sieges, or dungeons, there's a clear info section at the bottom left. It shows records of users who have cleared them, allowing you to copy their teams. Building a similar team based on those records can be very helpful for your own formations and setups.

Spending some time early on will help you out. There's a lot to do.
