L38 Patchwork Troll spawned waaay out of depth.

[HackOfAllTrades]

Attached is a screenshot of my new (and soon-to-be-slaughtered) halfling rogue. After clearing out the 3 main areas in Trollmire with relative ease, I enter the hidden area in the back and run into [this] behemoth. That can't be intentional, right? I know the area is a jump in difficulty, but it shouldn't be this bad!

If it makes a difference, I have all of the DLC, but no mods installed.
