I was wrong – Warhammer 40,000: Assault Dice Review

The dice do not strike and change the existing dice. If a die strikes a die the was previously rolled, it merely moves the dice to the side a bit, but ones not change the facing. The dice that are rolled. Together are the only dice that can have their result changed.
