While leveling I always started in the Drawf-Greenskin pairing. Adventuring in the Drawf-Greenskin pairing was always fun. This pairing has funny jokes going on.
While running around in Marsh of Madness one day, I was wading in the swamp when I came up to submerge barrels.
When I moved closer to them I got a popup about it was a Really Empty Barrel.
When I opened the barrel I got a Histroy & Lore Unlock and I learned about Greenskin Stupidity.
I can just see greenskins being scared of the ghosts in the marsh, climbing into the barrels and drowning. LOL
