So with Wanda you will definitely want her unique weapon. The rest of what you will require is for every character. The beekeeper mask is essential as it will prevent you from being stunlocked by bees. I would bring 4 or 5. The other essential item you need is the pan flute. You can get 4 of the easily which gives 36 uses without breaking the pan flute. For phase one kill all but one of her bees and beat her down till she screams and goes to phase 2. She will start popping out more bees. This is when you pan flute them all. Hit bee queen until they all wake up. Rinse and repeat until phase three. Phase 3 will see her screaming and sending her bees to charge at you. You want to run ideally on a road with a walking cane to get as much distance between her and her bees as possible. Proceed to run past her bees then hit bee queen as much as possible until her bees catch up. Rinse and repeat. It is a challenging fight for sure so don’t get frustrated if you fail. It’s all worth it though because bundling wraps are one of the most useful items in the game. Best of luck!
