The new form of the female wasn't changed much just a lot more shiny and big. Her size is about equal to his, both are longer than the bear was standing upright was tall.
She similarly got a second brain at the same spot, so they confirmed it was a mutation caused by the manuals practices.
Her mana could turn into flames, like the bear and she can produce light, but the light is unwieldy and not strong enough to damage anything it needs to.
So for now she can only wield flames which isn't bad.
Also in inspiration of the male's acid spits, she can spit fire pretty far, enough to be considered a mid range attack, with the range being about 1,5 sizes of their body length.

Now that both of them achieved the miracle of mana; they didn't do anything different than before, except they got more aggressive.
Additionally, they discovered through an accident of testing mana during the night is that, the stronger predators in the forest are nocturnal and wield, while simultaneously are attracted to strong light from fire and mana light.
So now they had a stronger prey and a way to get it quicker, even though the nocturnal were stronger overall and they were unaccustomed to night hunting, that didn't stop them.
Now they were against big cats, big wolves, big birds, big moths, and and an occasional monkey that just observed.
Like this the moved deeper into the forest with an with a snack here and there, slept during twilight hours, and hunted seriously during night.
During hunts they would use light to provoke any animal in the area and cause brawls between every one.
Since it was inefficient to fight with constantly pumping mana in the light, they fought in the dark using their sense of smell, touch and vibration sense.
As the days got by their sense got so sensitive that they could smell mana clearly and gouge strength from the mana being released during conformation, usually with them being the weaker party. Their senses of touch and limb position got so sensitive that they could fight with their back legs. Their vibration sense got so strong that the could formulate mental images through the movement in space of their adversaries.
At first it was kind difficult to fight like this, but they got used to it so much so, through their team work and the new mid range attack of the female, they could fight opponents with three times the mana scent.
And with all these fights, they acquired a lot of food, thus triggered a lot of moltings.
They doubled their length in a month, but the fun had to stop.
