Forgot to ask but do you think about giving Ashley some special skills that she can learn after leveled up? Like she can choose to learn some elemental magic attacks to deal more damages on the enemy or learn Lust based attacks to stun them and allowing your party to have more chance to kill without being hit back?
This would be complex to do because, in this battle mode, there is a big problem when adding new skills.
If I add new skills, they don't work on old saves.
So I usually plan everything that I want to add.
There will be a companion not in this next major update, but in a future major update that will have a big focus on magic. (He/she will learn new skills as they level up.)
There is a power I created where Ashley seduces the enemy and he is paralyzed for a while. (but it is very op.) It is already in the game, I just did not add it because I am still testing it.
Maybe I will put some way to add it when Ashley reaches level 10.
