Gistella came out of the forest and with one powerful leap clawed the Undead's head gruesomely, the head got sliced into three pieces because of getting slashed by her super sharp claws.
She then kept clawing the Undead that is clearly dead in a fit of anger.
The deathless Undead's blood decorates her claws while she kept clawing and stabbing, what's left of that deathless Undead is nothing but a very disfigured corpse that doesn't resemble anything of what its appearance was.
After venting her anger to the deathless Undead, Gistella sensed something.
Straightening her body like an arrow bearing her towering and muscular figure, she looks to her front with her sharp yellow eyes. Her vision is clouded with red clouds because of the anger she's feeling, but it didn't hinder her vision.
It's more like an amplifier of focus rather than a hindrance.
