Attacking army used attack boost (so a reroll when he lose or tie)
First roll: 15-15 (reroll) Second roll: 1-25 (attacking army lost his whole army and defending kept everything)
My idea: First i thoughed it was smart the pick the best rolls for the attacker... but what if the defender use a defence boost?!
so: If you have used an attack boost and have to reroll. You wont roll lower then your LAST roll. So the situatie i just told, the second roll would be prob end up like: 16-25 (worst case) and the defender still lost armies (on att mode)
