On her own, the most Herah did was just restore her brain after Norwe shattered it here:
‘How are you lost? You normally have no issue tracking me or anything down.’’ Herah thought with a confused look on her face.
A distorted and darkened image entered Herah’s mind, the youngling unable to make out anything but two black spots with specks of white floating behind them.
‘What the ash is that?’ Herah asked Jeffery, but before the pencil could respond the youngling felt the mental link between herself and her creation shatter.
“GAHH!”
Mental whiplash from the break struck Herah as her knees met the floor and her hands grabbed at the sides of her head. The youngling felt her psyche fragment into mere shards of itself before being forced back together by a surge of flames within her sharded thoughts.
Later on though, Jeffery breaks Norwe's hold over Herah here, right after making her give him her baby.
Once done with that, Norwe the Sloth compelled Herah to open up with their Presence. Once that was done, the youngling was then forced to offer up Ècarlate to her Maker.
Herah began to shake and her breaths began to come much quicker as Norwe’s claw neared her child’s head. Ècarlate seemed to sense their mother’s discomfort, shifting restlessly for a few seconds before turning their head toward her with a smile and reaching out to her.
“UGA-“
POP!
Herah froze as, before her very eyes, Ècarlate exploded with the sound of a wet pop into a shower of blood and organs bathing her torso, arms, and face in gore.
Ècarlate’s gore.
A newborn’s gore.
A newborn Cendruex’s gore.
Her baby’s gore.
And there was no healing nor flame in sight.
Once that realization settled in, Herah felt something inside her break as her eyes went back up to the still smiling Norwe. Tears began to pour from her eyes in waves as Herah stared at Norwe with a completely blank expression.
“But I love rebellion the most, when the rebel gets what they want. Especially, if it’s one over on me.” Norwe the Sloth said, no shift in tone at all as they pointed down to Herah’s arms, “Is that what you wanted artist? Your new kid de-“
“Mother I love you.”
Norwe paused at Herah’s hollow, dead words.
“Father I love you.”
The green flames still pouring from the side of Herah’s mouth began to darken and become blacker.
“La Flamme I love you.”
Herah’s right arm shot out to her side, Jeffery zooming into it without question before engulfing her in their Presence, Norwe’s hold over her broken.
That's why she has resistance to Mind Manipulation with Jeffery.
