I assume the battle between the girls and the Daves is the fight with Therese and Marsha. Therese does have a skill called Last Guardian that give her 80% damage reduction buff, but that buff can be easily removed by Davina's first skill, Dispel Strike. I actually almost put \c[10] (make the text red) and all caps the "cancel all their buffs" on Dispel Strike skill description, but I shelved that idea because it felt too passive-aggressive. Looking back, I should have done that.
Anyway, thanks for trying my game! Glad you love the art.
