Senran Kagura Peach Beach Splash: Der schnellste Weg, um XP/UR-Karten zu schleifen!

The final mission in Venus Cup takes 3,5 min, can reward you several 5 stars. It will reward you at least one if you beat it with a good margin (even got 3 UR once). However, you also get 10 000 zen which you can buy 10 packs for. Each pack can drop UR, (most I've gotten are 3 UR and 2 SSR in 1 pack, but that's really rare). I'd say it's more fun doing that mission and you could, if random loot lords are with you, potentially get much more from it. That said, you might also "just" get 1 UR and some minor stuff on the side as well. That said, you don't got load times etc. this way.

I've been getting a lot of 1* weapon cards, every time I finished a mission. So, I heard from somewhere that we can use these duplicate 1* cards to level up, but it seems that I couldn't find these 1* weapon cards that I've been getting ever since the first of playing this game. Is there any way to actually use these cards to lvl up ?

Thanks
