Dice are an integral component of Star Wars Destiny. At the start of the game you will have available to you the dice belonging to the characters which are revealed to your opponent; as the game progresses, new cards brought into play will add dice to your pool, increasing your options.
Some results can only be used if an associated Resource cost is spent. This is indicated by a yellow resource icon on the relevant face of the die. In this image, Kylo can only use that Melee Damage 2 attack if he spends 1 Resource.
Likewise, results with a blue background stack on top of results with a black background, and can only be used in conjunction with a result on a black background. In this image, Rey can only use that Melee Damage 2 attack if she uses another non-blue Melee Damage attack.

This symbol has special rules listed on the corresponding card. For instance, if you rolled a special symbol on the Sith Holocron die, you could spend the symbol to swap the Sith Holocron for a Blue ability upgrade from your hand and spend a resource to roll its die.
