Ah... Chapter 2.
I like a lot (but not alot) of things about this chapter. I like that it presents a tunnel complex as a series of connected events without a specific map. I like that it uses random encounters to build the structure, essentially making it play differently for each group. I like that there are both positive and negative random encounters on the list. These are good things.
But I also hate some things about it. There are 2 kinds of kobold traps and some weak-ass ambushes. The frequency of the crystals is also a bit of a bother. The average number of crystals you'll find is 2 (1-3). You have a 1 in 5 chance of finding crystals for each hour that you spend in the Wormwindings, and you need 6 crystals. That means that you will likely have to roll at least 15 times on the random encounter tables to find said 6 crystals.
Since the encounter table only has about 6 entries on it, statistically you're going to see them a number of times, which is not ideal. Makes the whole thing pretty repetitious, in fact. Of course, I haven't actually played it yet, but I'm not really willing to run risks on that, so I modified the table to give a higher chance of finding crystals. That way if the party wants to wander around looking for mineral/gem deposits, they can, but they are likely to find the crystals pretty fast.
I also don't really like the idea that the kobolds are going to be blocked off by collapsing the one passage. These are KOBOLDS. They get in places. That's what they do. So blocking the tunnel will provide a temporary relief from kobold incursions now, but not a permanent cessation. Of course, blocking the tunnel does have the benefit of heading off some of the random events that I added in Blindenstone Enhanced, so it's a trade-off.
So this chapter of Blingdenstone Enhanced features a full kobold lair, along with a 5e conversion of the Otyugh. Enjoy!

Since killing the little buggers is a standard method for control, here is a cheat sheet.

If you are using a VTT, here is the warren map file. Pretty sure I got it off Campaign Cartographer, but I went on a helluva downloading spree a while ago and didn't attribute everything.
