girlretard (npub1gv9…66j8) Agora Brewing (npub1zs6…ztmr) Reze is pretty strong. He's a breaker but he's kind of halfway between an attacker and breaker. Goes well with Rorona because both of their first attack weaken and they both can go very quickly after that
You also got free Shallistera, right? She's an area breaker, even if she's two stars, you might want to invest in her
If you get unlucky with pulls, Fire Resna, which is given for free, really, really quickly gets to 4 stars due to the awakening gems the game will give you for her via the mission/achievement list
