I don't really understand what this is. Is it an add on for the Dice Goblin rulebook? As such it has a lot of duplication with the basic rulebook. It is also not explained under what circumstances this fusion works. Nor how stability and instability (does it really need both stats?) are affected in the game.
Again, I miss the integration of the other dice. Why, for example, isn't the average of the stats taken and one cube category lower instead? Instability also mentions that decisions have to be made together. How does this work with NPCs?
Otherwise, the points are the same as in the DiceGoblin system. I like the other modules better.
