Skeletal Mage build - breaking barriers

Hello,
I am trying Skeletal Mage build. Sometimes I have a problem with the passing breakable doors and other obstacles. How do you handle it? I modified the build and use “Command skeletons” instead of “Bone Armor”. That’s enough for a fast GR.

The only ways to do it is to use the blood rush rune to generate a corpse, or use your golem active skill to do the same, with some essence pooled, then hover your cursor over the barrier or door and cast your mages. Mages always start attacking the target you had your mouse over when they are first cast.
