How do the face-painting items work: Lucky Die and White Paint?

Question

Accepted Answer

The Lucky Die lasts until the end of the scenario, so it doesn't carry into the next one. Face-painting items can be built more than once. White Paint only cancels the madness icon on Wound dice or Madness tokens, so it doesn't stop sanity loss in mystical combat. It can't be built in Episode 3, which has no plains.
