a more interesting rework definitely would be to give her unique combat abilities. She is a performer after all and not only in singing but you need to be dramatic as well. I really like The idea of having wigfrid do The spear dives from forge dodge rolls from wheeler even the multi attack while using the inspiration as a make shift stamina bar so that way its not spam able and it requires it to be earned through fighting.
My thoughts on it is that wigfrid is usually played as a tank, and gives no regard to taking damage she even gains inspiration from spiky bushes and cactus (I think she is secretly a mashochist). But she is at her best when played with skill. so i think it would be best to try and subtly teach the player to fight better with wigfrid. Since she is mostly chosen because of her abilities. i think we can keep some of the fight songs. health 1 sanity song the durability song and
just like how the scare song and the aggro song take a chunk of inspiration Why not have a battle command song that uses inspiration too But instead of it being an item to hold in your inventory it works more like a blueprint
or to help with inventory problem why not be able to combine songs together to save space and gain all effects.
Main thing i would want would be battle command stuff that can be done maybe with button inputs (maybe a bit like moose?)
Right click while moving= mini dash like forge spear
x3 attack input =multi attack like other forge spear with wigfrid
Battle spear exclusive = skydive attack at full inspiration.
just some ideas. maybe holding shift can prepare wigfrid for a roll and wig will roll in the direction she was going (has to be moving in the direction for at least .2 second maybe to help compensate for lag.)
There is lots of possibilities And the thing is Klei You have made all these assets already! Why not use them!
