Can Winter's Heart and Poly Stack?
No answers yet, so I’ll give my opinion. I’ll say no. You can’t mix two poly luminescents (the one that alter the color of the char itself). You can only be orange, black, green or teal. If you equip two different colors your char will be the second color you equip. It’s either/or for them. It’s the ones that don’t color the char but affect the area around the char (Ghostly, Queen Bee) that can be stacked.
Be careful what you ask for
