Temple of Horus I
The Shadow of Apophis immediately went towards the most important part of its body that it seeks. It wants to get he Venom Gland of Apophis as it already has the Fang of Apophis. The Shadow of Apophis can do physical damage but it does not have any magical damage which is why the physical tankers can easily ward its attacks off.
The western continent players have very built bodies that are durable to physical attacks. What the western continent players lack is the defense against magical damage. If the Shadow of Apophis wants to get the western continent under its feet then it should get the Venom Gland of Apophis first.
"The Temple of Horus should be my first attempt." The Shadow of Apophis thought as it already forgot the Sun God Ra since the other body is the one dealing with it.
