Mastering advanced combat techniques can make a huge difference. Learn to cancel Jonathan's whip attacks into sub-weapon uses for faster combos. Utilize Charlotte's 'Magic Seal' not just for bosses, but also to temporarily stun or debuff regular enemies. Practice 'Partner Guard' by holding 'Y' to have your partner block incoming projectiles, which can be invaluable in crowded rooms. Experiment with different sub-weapon and spell combinations to exploit enemy weaknesses. Don't forget about the 'Item Crash' ability for Jonathan's sub-weapons, which consumes a large amount of hearts but unleashes a powerful, screen-clearing attack. Timing your Dual Crushes for maximum impact is also a crucial skill to develop.
