The final core just made all of the monsters in the vicinity no longer care whether there are walls or trees on the way. They smash through all of them and they are now chasing me to wherever I am going. I have to do some parkour moves from all the obstacles that have been constantly blocking my way. It's already quite painful to see as most enemies keep on throwing obstacles at me and sometimes, they themselves will be blocking me. They are not something hard to kill but they become so annoying the more they appear before.
