At first Sam did not find anything even after checking the whole Boss room. Fortunately, just when he was able to stop searching for the teleportation symbol, Sam noticed something in the middle of that room.
You would not be able to find any pillar or anything like this. In the middle of the Boss room he noticed a tree that is quite different from those other trees.
Even though from outside everything will look the same. But after using the spiritual vision technique you would be able to see the difference. First of all, spiritual energy is dense in that area.
Well even though it is natural that many trees will also absorb spiritual energy, the consumption rate of the spiritual energy is not that high for those trees. Also if you look at that fake tree, then you will notice that somehow a barrier or something like this is present around that tree.
