Why do 4 level 1 earthquake spells take down walls? They don't do 100% damage. 4*6=24 24*4=96. Furthermore, if 96% damage is enough to take down walls, why don't three lvl 2 spells take down walls? Three lvl 2 spells do the exact same damage as 4 lvl 1 spells. 4*8=32 32*3=96. There is zero logic behind any of this, other than apparently somebody at supercell just randomly deciding that 4 spells is a lot so it should work
