Dragon Scale
From Talisman Wiki
The effects of dragon scales vary depending on whether they are placed on a Draconic Lord, the game board, or a character’s play area.
When a dragon scale is first drawn, it is placed on the matching Draconic Lord Card. The number of dragon scales on a Draconic Lord indicates how close he is to becoming the next Dragon King.
When a dragon scale is placed on the game board, characters may have to draw Dragon Cards when they encounter it on the space.
When a dragon scale is placed in a character’s play area, the character gains a bonus to his attack score for each dragon scale that matches his opponent.
