Reroll targets
If you still want to reroll to get more copies of specific units, I would only recommend two things:
- Reroll option 1: Aim to get a Creator / Destroyer character. They have lower percentage chance to drop on any banner so if you want to reroll for a good character, check our tier list to see what units are worth aiming for.
- Reroll option 2: Aim to get multiple copies of the current rate up banner. This of course will change depending on when you start playing, but guarantees you can save more pulls for future banners or have an easier time getting her to LR.
The last reason to avoid rerolling in STARSEED is that there are no limited units in the game, meaning you can always keep getting copies of the units you like even after their banners ends.
