After Olivia witnessed what Liam was doing, she purchased a batch of the Black Tarthear Needles as well.
She had asked him about the name of the needles previously but hesitated purchasing them because they were quite expensive.
Of course, their use was extremely high and Olivia was great with all weapons due to her Soultrait, Weaponry, but she could not magically learn how to wield a new weapon like a war veteran just because of her Soultrait. There were still existing limitations to the power of her Soultrait further marred by the physical limits of her body!
She handed a bunch of Black Tarthear needles to Rex, Kian, and the others before she charged forward in an attempt to help out Liam.
However, her attempt failed miserably. Not only was she barely of help but Olivia's life was on the line as well. She was nearly bitten and scratched by dozens of Plagued Monsters when she was trying to fight in a similar way as Liam.
