How have people been handling Low Magic and Theurgy against Cold Breath/Wards? It is unclear how these powers are meant to interact with suppressive powers like Cold Breath.
As far as wards go, on page 185 of the deluxe book it states "Empyrean wards do nothing to interfere with sorcery, whether in the form of low magic, theurgy, or minor magical items. These spells and devices function normally within their protected zones, even if they require the magus to Commit Effort to trigger their effects or quickly cast them."
Not sure about Cold Breath, I might handle that differently.
Cold Breath affects Effort expenditure, so I would only Low Magic or Theurgy that requires Effort to be spent is affected. This means that for Theurgy, casting slowly is safe. Casting Instant would be affected, for example.
I had forgotten that entry in Wards. I may have to add an additional factor to the Lomite powers then, because the info about the Pyre does indicate that the effect it produces allows for suppressing all powers. It might require committing Effort like Cold Breath just to use magic and theurgy, which means mortals would be outright hosed but mid-level Godbound would only be inconvenienced
