This entry concerns how this item interacts with chapter cards DCSE-CH22, and DCSE-CH42
In these chapters, the character who turned the chapter card is rendered incapable of mustering any WISDOM and MIGHT for the remainder of the chapter respectively. Think of it as all the symbols of that type disappearing from their character dice until the end of the chapter. If they roll a one of those symbols on their character dice it is considered to be a blank. However, if the affected player rolls a DOUBLE of that type, the shield symbol shown on the dice does apply - they have rolled a blank BLOCK.
This relic allows a player to modify their character dice to any symbol, but since the symbols are considered to have vanished from their character dice, the relic is of no use to the player in such chapters.
