Trap
When ambushing the team stayed within the edge of the path and the forest, but now that they are waiting for a longer time they decided to stay a bit deeper. But it seems like the rumors about the surroundings of the forbidden path are not completely false.
A large boar like beast is running towards the team. It is an Astral Plane Initiation stage beast. So, there was no problem for them to kill it at all.
They are quite surprised by the fact that a beast as weak as this will come at them directly. The beasts have better instincts that many creatures, this should have normally ran far way from them, but instead ran straight towards them.
Sam started checking the corpse. The first clear and major difference is that the blood of the beast is blue. From the looks of the beast, he could guess that it is Metal-tusk boar. But that boar wouldn't have blue blood which is quite a surprise.
