I did the first half ("Part One") of Feywild in a loooooong session last night. Level 5-6 (mostly 5).
It's fun, and with variation on quests like I've never seen that before. The environment is also … interesting.
The story is solid, but not as emotionally touching as Ravenloft of Lost Gatekeepers, which I find a pity. But, still, it is solid.
There's lots of social interaction. Not that much skill checks - alsthough that helps, because there indeed are a few - but also lots of asking NPCs to proceed through the quest's story line. Much like Mad Tea Party of Ravenloft.
There's a few surprises as well, story-wise. At least there were for me.
The quest areas are sometimes a LOT of travelling time from the castle hub. I don't remember right now whether there is a … uh, what's the word ? … teleporting man ? in the castle.
The artwork is quite nice. It varies, and there often is nothing like expected. especially regarding trainers in the castle.
@Corwin; : The Hirelings (pemanent) come i think only with the highest tier of the Expansion.
Fun fact : They have a slightly different look each time they re called (differently coloured clothing, for example). They are called "Feywild Muse", and that rather generic name fits, because they are just like that.
I can't shake the feeling as if they had been updating the Hireling's AI a little bit. But maybe that's just a personal impression, I don't know. They can heal a bit, do soundburst a bit, do swordwork a bit. Most notably, however, is, that they are much slower running than standard Hirelings. In my play, they were always lagging behind a bit.
General note : In the Feywild, things are always a bit different.
A new crafting ingredient are Ferrocrystal (?) items … I didn't find a crafting device yet, though.
Some items with this material (effectively it's crystal) are also dropping. Playing on normal got me only 1 item so far. (A crossbow.)
Sadly I haven't had anything beside that yet, but, as we discussed that before, grouping has much better drops in general.
The only thing that really irritated me is that there are sometimes "invisible walls" at the quest area's borders. Sometimes where you don't expect them to be there.
The second real disappointment for me, personally, is the size : It's much smaller as Sharn - or so it appears to me. I haven't seen only a half of everything so far, though.
But … this is in part balanced out by the sheer love for the detail. Pixies, I say !
As a sidenote, even if you have music turned off, you'll hear the Reveler's (Satyr's) music regardless, if you meet them, but since it's fun and energetic music (reminding me of traditional Irish music, which kind of fits), it isn't bad at all, imho.
So far, I like the Expansion very much.
