The attacking player can resolve any abilities or spend any aim tokens that allow the attacking unit to reroll attack dice. A unit may spend any number of aim tokens while it is attacking to reroll up to two different attack dice for each aim token spent.If a unit has multiple aim tokens, that unit can choose to spend each aim token after determining the results of any previous rerolls granted by aim tokens.A unit may reroll the same die multiple times by spending multiple aim tokens, but each die may only be rerolled once per aim token.
