The swamp is full of spear traps: they are very well hidden and are very quick, if you exam the terrain accuratelly you'll see the holes in the terrain from where the blades (or spears) come out. Due to the fact that these are not explosive or poisonous traps it seems like party is taking seldom damage.
I've been hit by those, but they have the little dice perception check failing before it happens.
This time it's not traps - this is inside the Druids Grove, steps away from the forge and where Auntie Ethel first appears near the woman handing out gruel so I know it's not trapped.
Also Wyll was going about starting fights with people just by standing near them, it was all very strange.
