The title says it all. If I say have Impervious on my dial and invincible from a resource do they layer like impervious+supersenses? Just wondering cause one reduces and the other ignores. Thanks in advance

No. A character can only use one effect that ignores or reduces damage at a time.

You would be able to choose which one to use each time the character would be damaged, but not both on the same instance of damage.

One or the other. Not both.
