Just curious if you can cause any companion movement. I was solo'ing the hammer instance and had no issue until the end boss fight. She got a ring of dmg placed at her feet. No big, except she never leaves it. It just increases in the dmg dealt and one step to the left would solve it. But yea, I can't seem to make her do that. You think the AI would move.

One of the skills on a companion's skillbar is "Passive" - second skill, next to 'Attack'.

When you put the companion on 'passive' they stop healing/attacking and come over to where you are to wait 'passively' until you reactivate them.

So next time, put the comp on 'passive' until it moves out of the circle, then put it back on 'active'.

I did try this work around. Unfortunately the boss just recast on top of my companion consecutively. So, I can spam doing this, but then can't dps the boss and the constant interuption to heals just isn't working. Seems I just won't be able to solo this boss.

Try using a 'melee' companion as a healer. If I recall, the boss doesn't tend to drop those circles around himself.
