Or just leaving on minor metal things?

The things that are getting you, are metal body armor, legs, arms, boots. In all seriousness, remove those and you can laugh at their wasted mana. Having metal weapons alone does not make telluric surge do damange or movement drain - making it a far less effective prayer.

With Jichii, I for some reason had an outlander druid constantly gunning for me in the low ranks. I didn't have much chance to kill them, but I found removing all my metal not only didn't impact my ability just to defend from them - but made the druid use fireseeds which I could save against far more easily and let me escape. As long as I stuck to civilized places to escape the druid, entangle wasn't a fear either.

It's like Magus said, if you know their weaknesses it's far easier.
