Helpful Rise Tech for the Margaret Fight
I noticed that if Chie uses Dragon Hustle every 3rd turn, Rise will almost always give the party Power/Mind charge when she uses her persona.
It would help to have a party member at high HP/SP to make her less likely to use those boosts. During my fight, Yu frequently had high HP because of Izanagi-no-Okami’s resistances, and Yosuke maintained high SP due to spamming Brave Blade (with a rudra ring) instead of Garudyne.
Of course, this is complete overkill for any other fight, even Izanami, since the amount of SP recovery items Chie needs to take to maintain the stat buffs is quite substantial. But, if paired with Yu spamming Debilitate on Margaret and Evade skills, it makes your party members almost unhittable on their weaknesses, making the fight a lot easier.
