An idea I had, just for kicks.
When the Monster is sneaking, slowly diminish armor glow. So I’ll start off glowing like a Christmas tree but slowly become darker and darker. However, when you stand up again you momentarily flash much brighter before returning to normal.
The main reason I want this is so that I can sit in a bush, be perfectly dark and invisible, then stand up and suddenly be glowing and on fire. Surprise.
For kicks and giggles. I don’t know.
