Can Love Blossom in a Poisoned Heart? - Chapter 47

I am so confused. She was learninymagic and knew fire magic, spatial magic and so on yet she carries a chair to protect them? She knows magic but can’t find a cure to go uncovered under the sun? She knows magic and has inhumane strength yet get her hair pulled by a spoiled bimbo who doesn’t grow? The ML knows how to fight only when convenient because apparently he cannot defeat bandits, or monsters or ambushes.. what a joke
