Breakdown of how the gacha system works
To simplify this, this system is not like endfield like many others believe, its closer to pre hoyoverse gachas, basically like a gacha made around 15 years ago
Spark system at 100 pulls for characters and 80 for weapons
No soft pity
No 50-50 doesnt mean that your next 5* will be the featured, it means the 5 star motive/characters its divided between the featured and the standard, the standard are gratia, rex and Cynthia, and it does say the featured character gets a higher rate up, we dont know how much is it, so assuming it barely changes the %, realistically you're looking at 25/75 for motives and characters
And since theres no soft pity, it means you're usually not gonna get many 5 stars before you hit the spark
The system seems to have at least a carry over with the spark, so you can end the banner at 50/100 and you will just need to pull 50 more times for the spark of the upcoming character
I'd be nice to know at least how much is the % rate up for featured characters and motive but i doubt it will increase to 40-60 or something like that considering they're not showing it off
