Well, I finished the DLC. The level design is actually quite good... I liked it a lot more than any area in the base game. It's more or less on par with Dark Souls 1, which is high praise indeed. It's fun to play with the mechanisms and find all of the hidden passages and shortcuts. The place looks gorgeous and atmospheric, and I love the twisted, off-kilter entry passageway to the whole zone.
Unfortunately, there's not a lot to actually find down there. The new items are few and uninteresting. I really want to like the
, but it has pretty bad stats and seems to break easily. There's no one at all to talk to down there, unless I missed someone. The only new voice acting I can recall is a couple of one-liners from one of the bosses. There's one inspired enemy type that everyone is gushing about, but aside from that everything is very by the numbers and dull. I hope you like big hollow knights with high poise and slow melee attacks, because that's easily 50% of the enemy count.
Two of the boss battles are straight up bad. Havel and Friends are probably the laziest excuse for a boss in the entire series. They also build on the terrible enemy design from Dragon Shrine: melee enemies with infinite stamina and unpredictable combos so there's never, ever a safe time to attack them. These fights aren't a fun challenge, and there's nothing interesting about them. They just give truth to the lie that Souls games are cheap and unfair.
Elana is also pretty lazy, but I'm less upset about her. At least the dragon was a cool boss fight.
Overall, I'd say this DLC is solidly below Artorias of the Abyss. If the next two chapters are of similar quality, we might end up with three quality areas and three good boss battles between them. That would put us on par with Artorias, albeit at twice the price.
