I think it was thumbs on a marilith, not wrists. Not that that makes it a different answer. Also, if you do the challenge from ... the Pickle guy (not his real name) you have to solve a few riddles. One of the answers is wrong, although reflecting on it that may be part of the shtick for that particular mission.
The autohit + autocrit on all attacks was a brutal bug to leave us with over the weekend. It made testing higher level missions suicidal in some cases, and irritating because of the expensive hiring fees. At least they have specifically said it was one of the things that was getting fixed Thursday in time for the Open beta portion. Stacking the -1 speed penalty for heavy armor on top of Slow is a little odd, but will hopefully go away as well, and I won't miss all the extra clicks for no real benefit introduced by the new UI.
Some of the complaining about the brakes they put on the ability to chain together dungeons stems from folks having something taken away, anyone starting anew wouldn't notice it so much. They had to do something though, to keep people playing instead of finishing quickly and burning out, and making everything take longer is always easier than adding content (see: every mmorpg, ever.). There is also a fair amount of complaining from folks unaware of what "beta" means, but, you know, the internet. Recruiting friends is still gold-free, and nobody has an answer that increasing gold drops for the people who don't stockpile facefriends so they can recruit to do adventures that doesn't hand over control of the gold supply to the people that have dozens of friends. Bypassing the cooldown with astral diamonds seems pretty solid, whether 1 per recruit or maybe a flat fee to bypass it for the day.
The player made dungeons are a bit of a problem, since it looks too easy to make powerlevelling dungeons. I don't know if it's good or bad that the player made runs can't give out more loot, but I do know that I am tired of grouping with 10th level people still wearing their starting equipment that (until the last patch anyway) couldn't hit, did weak damage, always get hit, never make saves and pump out anemic heals. With no gold, they can't buy the expensive gear for their level unless they can get twinked, although if they have lots of friends running actual adventures I guess they can get gifted enough gold to make up a little of it.
The quick and dirty character creation process is fine, and even the limited power selection isn't that bad for launch. It gives an easy upgrade path to add content, even if all they do is add races, classes and powers. The lack of OAs or defender marking really hits home how cool those features are in 4E, so I hope something is introduced along those lines to help the poor fighter at least impede the bad guy's tactics beyond his couple of slows and a prone. The only power progression that looks out of place is the poor cleric, who if he skips taking Cure Light Wounds at 2nd level only has 1 heal per encounter until at least 5th level - where his next 'healing' choice is amusingly enough Raise Dead.
Lastly, I think the tooltips and descriptions could be cleaned up. Some spells have the same description, but perform differently (Lightning Bolt and Fireball are both merely area burst spells). If you don't have a rogue or he fails to open a lock, you can buy a Knock scroll - however the descriptive on it seems to strongly imply that you get 5 knock scrolls for 1 AD instead of the actual 5 ADs per 1 Knock scroll. The first time you run into it, its appearances in the rest of the game become clear; you don't get 15 Potions of Life for 1 AD, or whatever the ratio on Potions of Luck are or whatever. The first time you do it, it's a bit of a surprise.
All in all, a pretty good game for free. Easily playable without ever spending a dime, and just as easily to spend some money on and feel like you got some value for it.
