So true, sad they are the only thing in this game that has that weakness, all the other enemies are much more annoying
While this page has the correct title for the enemy, the other page (http://darksouls3.wiki.fextralife.com/Hollow+Slave) is much more detailed. Could some admin remove this one and rename the other one to Thrall or something similar?
