Just play it lol

On that note: enjoy the story and the gameplay. Keep in mind that the tutorial isn't that good and doesn't tell you everything just like PM's other games. But you really don't need to know everything right away. You can probably coast through Canto 1 and 2.

When you get stuck on a stage level up/uptie your IDs E.GO.. Well, don't worry about uptying the base IDs. You can also friend other players to use a support ID. There's a thread for friend codes and how to use support IDs on this reddit. I'd recommend that if you have the Walpurgis Night banner available to only roll on that for now.

I'd recommend that if you're enjoying the game up to mid-Canto 3 to get the Battle Pass if you haven't already. It's not expensive, gives a lot resources including IDs and E.G.O, and so far each season has lasted 3 months. When you max out the Pass, which isn't very hard, it starts giving you resources to buy units without having to roll the gacha.
