Is there a way to make my Arcane Orbit Melee Wizard attack closer to Enemies?

[jerryscherry123]

I have a Melee arcane orb wizard. Is there anyway where i can make the wizard get closer to enemies so that the orbs explode? sometimes it will just be using spectral blade just far enough so the arcane orbits orbs wont be touching the enemy

also is there anyway i can increase the bot to use spectral blade more? sometimes i just sits and waits, but i use barrier blades so every time i attack my barrier goes on, but if it sits there without attacking i will take more damage

let me know thanks
