Scout bombs are a versatile tool that are most effective when the defender is offline.
Scout bombs (SB) target the highest total attack group.
So if there are 100k archers and 150k warriors, because the archers have a higher attack than warriors, the SBs will hit archers.

  • Archers:Workers  1:24
