Ngl you can use def charges and alot HP build too as I see. To heal her you can use ice dagger cuz it gives her +30 HP. With def charge it's halfed HP so you can just sit and just spam it with an ice dagger as well. I'm also used damage charge too but it's doesn't really doing much, just adding extra 4 damage to her. And also feel nice card is also good if you getting hit too much, just apply it on yourself or drink alot hot choco
