Actually .. The formula above is correct.

In formula you use, the total amount of damage would decrease the more spells you use;)

Example : 3 max spells on 100hp building

Expectation: 100 - (12% of 100)= 88 88 - (12% of 88)= 77 77 - (12% of 77) = 68 hp left

Above formula: ((1-0.12)^3)*100 = (0.88^3)*100 = 0.681472*100 = 68 hp left

Your formula: (1-0.12^3)*100 = (1-0.001728)*100 = 99.998272 = 100 hp left ( nothing lost??)
