Blasters are limited by line of sight and they cannot fire at anything higher then themselves. They can sometimes destroy creeper not in their LOS if they fire on a square that is adjacent(or very near) to it and the square outside their LOS will be counted towards the squares they damage. To shallow (1 elevation or less) creeper a blaster damages 8 squares removing 1 layer(all) of creeper. To deeper (more than 1 elevation) creeper a blaster damages 7 squares dealing 2 ccc damage to the square they fire at and 1 ccc damage to 6 adjacent. Blasters can also benefit from “trough the wall” damage mechanics.
