Yeah, you're supposed to "share" the "burden" with her. I think some dialog or something in there says something to that effect. But it's rather annoying to execute, at least I felt so. Trying to stand in the circle while being continuously passively pushed out, while avoiding the appearing danger wedges which completely knock you out, while your health is constantly draining, while you're being ranged-attacked by ley-line dudes... Multiple times I had to back off and just stand around waiting for my heal skill to recharge so I could bring my health back up enough to bother trying to stand in the circle. And several times I would get knocked out (not even sure why, I swear I was avoiding the knockback wedge) and what little progress I had would drain away, just making the whole thing take longer.
