Why is Virtue Silver (a metal) mask Leather only? Headless Mask (which has no materials) leather only? Snowman is cloth.... Ice Nightmare is Leather... are there any even for Heavy? Why not just make masks apply to whatever armor type you want instead of making them limited? Having a snowman head on doesn't indicate what type of armor the person is wearing in any form, and helms can be hidden now anyway. Masks are a great opportunity for RP but they should have some more liberal application of their patterns.
