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 creeper a blaster damages 8 squares dealing 1ccc damage:

This will happen when the creeper is up to 1 elevation level deep. On the left you see a blaster firing into very thin creeper and damaging 8 cells. The damage of this shot is probably less than 1 ccc (8 x 0.1 ccc). On the right you see a blaster firing into creeper of exactly 1 elevation layer deep. The damage of this shot is the maximum you can get: 8 ccc (8 x 1 ccc).

For deep creeper a blaster will damage 7 squares dealing 2ccc damage to the square it hits.

This will happen when the creeper is more than 1 elevation level deep. On the left you see a blaster firing into a pool with creeper of about 1.8 layers deep. The shot does the maximum of 2 ccc damage to the cell it targets, plus a maximum of 1 ccc to 6 neighboring cells, so in this case the damage is 1.8 + 6 x 1 = 7.8 ccc. On the right you see a blaster firing into creeper of exactly 2 layers deep. Again the shot does the maximum damage of 2 ccc to the target cell, plus 1 ccc damage to 6 neighboring cells, which makes a total of 8 ccc (again max. damage for 1 shot). When the creeper would be deeper than 2 layers, let's say 3 elevation levels deep, a shot would do exactly the same thing, leaving some creeper in all damaged cells. The maximum damage of 2 ccc for the target cell is also the reason spores with an intensity higher than 2 can't be taken out by a blaster with 1 shot when hitting the surface.

If you drop a blaster into creeper damage will be done the following way:

On the left you see a blaster dropping into shallow creeper; 8 cells are damaged in this pattern:

111
110
111

On the right you see a blaster dropping into deeper creeper; 7 cells are damaged in this pattern:

111
020
111

One blaster shot costs 0.2 energy, so it can fire 5 times on 1 unit of energy, which makes the maximum damage per unit of energy 5 x 8 = 40 ccc. When you realize that a mortar shot does a maximum damage of 42.4 ccc per unit of energy, you can easily conclude that dropping blasters into a pool of creeper is just as effective as using mortars. Of course this isn't the case when you let them target shallow creeper at the edge of a plain. However a fully charged mortar can do up to 1152 damage as it has more ammo capacity whereas a blaster can only do 400. So when using them away from base mortars still win.

Blasters can benefit from "trough the wall mechanics"
