Because I am a spectacularly bad loser, decided to spend quite a bit of time and a major of resources into experimenting with new gear - with damage modifiers for Darkspawn.
I then returned to the area I spent over an hour on before and tore everything in it a new arsehole, with sides of dismemberment, impaling, beheading, general maiming, frying, freezing, burning with the odd bit of dispelling thrown in. It was utterly nuts how fast enemies died - it was also utterly glorious.
The subsequent section, however, show just how unbalanced it was and what a major spike of difficulty it is. As, after that, with new enemies turning up, I'm still going through them with ease. It was mad.
Cue the end-of-DLC boss and it's another frigging difficulty spike, even higher than that infamous mid-point one. This time it is a boss who does one-hit KOs or hits you off the platform for near instant death. It sounds cheap? Damn straight it is. Playing fair I got it down to about 25% health, then it just kept whacking off the platform. There is but one solution for cheap bosses - Death by Cheese. This one works by you getting knocked off the platform and not moving at all when you get placed back on it - by staying put the boss can't hit you but you can hit the boss. So did that, took a few minutes but it died.
So 2 DLC down, Trespasser remains. So far, I'd rank Hakkon way above Descent - they do share similar flaws, overpowered enemies, spikes without warning but at least Frostback Basin was more interesting to explore. I did like that you could order the building of hugely intricate bridges in the Deep Roads to access new areas. That was smart.
Should you consider it? Depends - are you willing to cheat to win because I see no fair way of taking the final boss out. And if you buy it you better be prepared to do Batman-level preparations.
