My spell is just below, and if someone can modify the spell so it does not attack to the specified area every time that would be great.

I should probably give some examples because even I am slightly confused O:

Currently the following effect;
- Player casts spell
- Player shots 4 times, which is fine however every time the spell is executed, it is going to use the following 'myArray', in this case it will be; 9 hits for 1 spell execution (9 is a random number and can vary, dont worry about that)

I was hoping to create something like this instead:
- Player casts spell
- Players shots 4 times, but this time; only 1 hit for 1 spell execution (the spell is being executed 4 times)

I see where you going with 'true', but unfortunately it does not work

Nice, but array will stay the same once loaded. I was trying to add for loop but I've noticed the array is not changing >.<, i.e. we cannot do something like this: myArray[3][1] = 0 - Well, in theory we can, and the array will change when we print the result in console, but the effect will stay on the same position as when loaded.

Which ultimately means; once the spell is loaded and math.random defined, it will hit the same spot over and over again (in your case);

that's why there's: return math.random(2) == 1 and ...

Thank you for your time though, I hope someone can help me with this unless you have better idea
