CDproject always played with the lore a bit loose, so I’m sure the explanation will not be in line with book canon, but hopefuly it will be a good one.
My guess is some modified version of the Trials, less powerful but also less risky - maybe made possible due to her “herbal treatment” at Kaer Morhen. Or she just resumed the herbal treatment long term and these are the results.
