So, what if, now i know theres a small chance of this ever happening. BUT WHAT IF!
When consuming the frame, the helminth spits out the Forma/Umbra forma inside of it because... Reasons!
This way we can get our already invested forma's back and we can ammend mistakes that were made by umbra-formaing a frame that hasnt been primed yet/isnt primed for a long while and we want to be able to reinvest that umbral forma.
Its a small suggestion but i feel like this could make the Helminth that much more useable for everyone.
