Kili was quick to scramble to his feet, panicked to see one of the spiders pierce Saeril. With an angered shout, he swung his sword at one of the spider's 8 legs and hacked it clean off. With speed on Kili's side, he managed to cut off another before he too was hit, then drug down. If the spiders had their way, they would proceed to wrap their victims.

One by one, Bilbo cut the dwarves down from their makeshift prisons. Each was woken from the impact, and each freed themselves from the overly sticky webbing. 
"Thorin! They need our help!" Dwalin called as he saw Kili and Saeril, his axe drawn and ready. Thorin moved in to attack, and the rest of the company also got to work taking the terrible creatures down.
