Stardust DISCUSSIONS › Category: GAME RULES › Stardust 0 Vote Up Vote Down Stephen asked 4 years ago can you use stardust to provide +2 battle strength with unbound? 1 Answers 0 Vote Up Vote Down battalia Staff answered 4 years ago Yes, Stephen, you may. Wherever you need supply card you could use stardust instead. The only thing you’re not allowed to do is to split the stardust card between 2 actions (similar to the tools card).
