I'm scouting GDs from outside the wall that surrounds the Fire Temple. The stuff inside the temple followed me along the East wall, along the North wall and then down the West wall. The moment I turned the corner onto the short South wall, everyone started dumping on me! 2 Drags an GD just let it all go! Almost died from the paras, poisons, flamestrikes, etc. So I went back to the short South wall in the middle of the East wall and a Giant Serpent was able to attack me through parts of that wall. The Devs must have worked overtime creating some walls that are porous to magery, some that allow physical damage and other walls that allow neither.
