all of my mimbranes have trust level 4 but i don't know how to get the face mimbrane
You need the feet mims which require human feet. Digi legs are SOL and it sucks.
You don't. As a half kui-tan without the feet I got the face
I had to get feet to get face, either you bugged and got lucky or something changed. Also, in case you weren't aware, kui-tan feet/legs are human, just with fur.
I got the face, became a slime, then lost the legs but kept the face.
Well that seems like a loophole, mims should stop leg tfs, especially losing them.
GaloMax specifically removes them when the fifth dose takes effect.
I don't remember if there's a description of them leaving when you take the GaloMax but it's specifically coded to happen. Are you saying lore-wise it shouldn't?
