Kelia had to admit that she had been reckless while dealing with monsters, hostile Emperor Beasts, and plant folk that threatened Wyrmhold but there was a reason she was so confident in her abilities.
Her equipment had been crafted by Baba Yaga herself and it was made of Davross.
Also, as the host of the Horseman of Dusk, even though she had a bright green mana core she was harder to kill than a Divine Beast. Kelia rushed into battle not because of youthful stupidity but to gain invaluable experience.
With Dusk and her equipment, she could take risks that no one else could. By putting herself into life-or-death situations, she honed her battle instinct and learned to suppress fear and hesitation in the face of stronger opponents.
'What point does it have to have an immortal body if I keep being afraid of getting hurt?' She thought. 'Baba Yaga's seal doesn't affect Dusk's regenerative abilities. I can afford to take one death blow or two if it means killing my enemy.'
