Advice for beginners (Blue Archive)

She's a meta character and strong, but she's a supporter. Not a damage dealer. Blue Archive has tanks, attackers, and supporters. The rest depends on the situation. First, level her up. It's a game where you get stronger slowly by doing events. Also, I can't give detailed advice without knowing your roster. Start by raising one tank and one attacker. Most people haven't finished their training yet, so take your time and don't rush.

When talking about efficient strategies, first, focus on raising a small number of students (resources tend to be scarce in the early game). Raise Tsubaki, a super strong tank (she's easy to get at 2 stars and very durable. Plus, she's useful for BOSS mechanics in modes like Total Assault). Swimsuit Hoshino is a very strong supporter, so keep raising her. It's recommended to have her use her skill at the very beginning of combat. For a healer, raise Serina (she's a 1-star student, easy to get, and while her healing is single-target, the amount is very high. She can also move allies with her skill. Moving your tank can be used to separate them from other allies during a boss's AoE attack). For your damage dealers, AoE skills are recommended (single-target high-damage skills are for bosses, while AoE skills are for clearing mobs. In the early game, you're more likely to lose to mobs chipping away at your HP than to bosses, so AoE skills are effective).
