As Guissepo had stated, blessings which were given to those who wanted to become combatants before they entered the Foundation Stage never truly became useful unless they advanced very far in their strength – core, class or stage – or cleared quite the amount of high level Clusters.
(A/N: For more clarity or if you've forgotten, refer to Chapter 158).
Gertreld was the only one in the Harem's Guild to have a blessing that had already become relevant to her fighting style.
This was because of her background.
She was from the Godrigold Family, a rather wealthy family that laid claim to a large region in the North of Pelian.
The Family Head had been 'cursed', in his own words, to only have daughters no matter how many women he bedded.
Thus, he decided to at least fashion these women to be both upright, smart and strong as he refused to pass his wealth to a bastard or worse.
