How to let Handles.DrawLine under GameObject?

I use Handles.DrawLine to show some area about our skill of the boss.
It seems that the line was overlay on the boss.
Since I want to the line under the boss, how to hack this operation?

Thanks for the reply.

According to the documentation, Handles.DrawLine() is editor only, so you don’t want it for a finished game anyway.

What you probably want instead, is LineRenderer, which is far more customizable.
