The sting pierced Saeril in the left arm, and she felt the numbness throughout her body, almost as if she was stiff inside out (almost like her arm fell asleep). The injury on her leg was healed, but this was another injury she would have to fight through. She and Kili couldn't momentarily move, while under the effects of the spiders' poison in their bloodstream.

The she-elf realized that the company was outnumbered by the arachnids, but she didn't expect Elves to appear out of the trees, some shooting at the spiders with arrows, while others used knives. That's when Legolas appeared, using his arrows and knives to kill the spiders, after which, they point their arrows at the dwarves and the she-elf. "Do not think I won't kill you, Dwarf. It would be my pleasure", he firmly told Thorin as he kept his stance in front of him, with the arrow aimed at his face.
