As a Bronze Age guy I normally futz around the edge of the swamp grabbing some blood bags and entrails. One area I was very familiar with was yielding its regular drops when I saw a weird looking stump. The thought occurred to me that this might be the new swamp 'thing'. I put an arrow into it from a decent distance. And yes, it was an Abomination in every sense of the word.

Gear-wise I wasn't really set up for it and merely confirmed what people had said about lower end arrows not really doing much. Similar to trolls, it didn't really chase me down as I was retreating into a Meadows biome. It rated about a 8.5 on the creep factor with me and it's now hard to look at the swamp without extra apprehension. I look forward to killing one once I'm prepped.
