For the illusion circles indicator next to the shatter skills, be able click on each circle to disable shattering of that illusion . In addition, instead of three circles, have four circles that correspond to each shatter skill and on additional clicks, be able to assign each circle to any of the shatter skills. On a last click that circle goes back to normal shattering. In turn this allows toggling between different shatters to be used and which ones to not shatter. A fifth shatter all illusions skill might be useful to shatter all combinations at once. f1-f4 skills would be to shatter ones self or to shatter any circles assigned to it or to shatter any normal enabled circle.
Using shatter effect icons inside circles will show what effect is assigned to that circle.
There may be some redundancies but that can surely be worked out somehow.
