@yukinoh1989 sure, its a bit convoluted so I do not blame you

First we start with a cube, and ersa both the top and bottom faces

We create a empty that will be our point of reference of the modifier on the origin of the cube, and apply a subdivision surface [simple not cammul clark], to make sure we have enough geometry to work with.

Then we can add the simple deform modifier for the twist using the empty as origin and selecting the proper axis, in this case Z

But you will notice that if you try to add an array now with the default 45 degrees, the faces will not coincide, so, we will add an array modifier BEFORE, the simple deform, and adjust the lenght with this array, and set the angle of the simple defomr to 90 degrees, then we will add a second array, and this time the faces will coincide, remember to check merge on the array modifier and set the merge distance if needed

After that we add a subdivision surface and object->shade smoth, and we get the twist.

This is a bit more convoluted than needed really, you can jsut add an array to the cube to get the height you want, then add the simple deform->twist modifier and jsut set the angle to get the desired twist, I jsut happend to do an extra step there.
