Plot Twist: This is all self fulfilling prophesy , the reason why his territory is destroyed is because he gathered them all (like human polity invaded) and something happened to him thus they went out in a rampage to avenge him. (Not a spoiler)
Because all of the talk of Siana being on "the deepest floor" provides no clear number to it, I'm just going to assume at this point that that number is "three."
Dude didn't even notice he targeted Sia with the water spell from the staff? Holy moly that's a dangerous personality. Out of all 360 degrees around him, he instinctively chose the one direction where his ally was standing.
I understand his reasoning to level up by drowning dungeons. But going by the picture on page 19, can someone explain how zombies and skeletons can drown?..
