D&D 5E Free 'Descent into the Lost Caverns of Tsojcanth' Adventure on D&D Beyond

Descent into the Lost Caverns of Tsojcanth is an abridged version of the full adventure, which appears in Quests from the Infinite Staircase. You can access it for free on D&D Beyond.

Deep in the Yatil Mountains lie the Lost Caverns of Tsojcanth, formerly occupied by the legendary archmage Iggwilv the Witch Queen. Though Iggwilv is long gone, her lair is anything but empty. Demons, giants, and other formidable creatures haunt the perilous caverns, and the archmage’s magical defenses remain intact. The rewards for braving these threats defy imagination. Iggwilv is rumored to have amassed a magical hoard of unsurpassed value, a trove of such fame that scores of adventurers have perished in search of it.

This supplement is part of a yearlong celebration of Dungeons & Dragons and its 50th anniversary. The adventure presented herein is an abridged, quick-play version of “The Lost Caverns of Tsojcanth,” which appears in Quests from the Infinite Staircase. See that book for the full adventure.

“Descent into the Lost Caverns of Tsojcanth” is designed for four to six 9th-level characters.

How does DDB still not have a "things I own" section or filter. That's so basic

They can't sell you more content if they don't show you all the stuff they can sell you.

Actually, the formorians should cost you $1.99. I've done a lot of a la carte purchasing from DNDB, and I vastly prefer it to being forced to buy the whole book for $30.

The link on my desktop took me to the $30 product - I must've missed the $1.99 option.
But c'mon, is it too much to include the stats of the relevant monsters in the adventure? Like, if I bought the physical book there would be an appendix of creatures, right? Do they do this with Beyond?

They can't sell you more content if they don't show you all the stuff they can sell you.

Since I stopped buying stuff on DDB after Spelljammer, there are now many items that show up in my searches that I click on and take me to a Buy This Here page. It's very frustrating that you can't filter out things you don't own.

Oh my goodness yes this! The filter could use a lot of work.

believe the original adventure -- mine is in storage at the moment -- included both the greater and lesser caverns, while this only includes the lesser level.

the book will have both, the four hour one-shot / tournament version does not

The great monster book that came with S4 -- which formed a large part of the Monster Manual II -- has been so thoroughly raided in subsequent years that the only new/returning monster in the 5E version is the pech, which probably doesn't really need a stat block. They're NPCs from the Plane of Earth who like mining and aren't looking for trouble. (The 2014 Monster Manual doesn't have stat blocks for "dwarf miner," for instance. Some stuff is just background flavor, IMO.)

Demon Skin is a fantastic magic item. It's new to me, but I can see it being incredibly popular. And it's very creepy.

Very retro having a new magical horn. Are these a very popular class of magic item? TSR/WotC has had them around for years, but I never hear about them being used. Heck, I keep forgetting my "horn of summoning those weird ogres from Act I" I have in Baldur's Gate 3.

The rainbow potion is a renamed 1E magic item, I believe.

I like them leaning into Iggwilv's witchiness with a boat that has duck feet. Not a great magic item -- it's slower than existing land or water vehicles -- but it's got style for days, for the right character.

The premade dwarf with the metal teeth doesn't have anything explaining them on his character sheet, alas. Pretty fun image, though.

I believe the original adventure -- mine is in storage at the moment -- included both the greater and lesser caverns, while this only includes the lesser level. I bet they handle the Lost City in a similar fashion, by just focusing on the areas that were previously detailed and leave the undetailed sections for the DM to create, as always.

The rest of the Caves are coming in the full book.

The Lost City is supposed to get the bottom levels fleshed out.

It does. Things you own don’t show up in the marketplace.

I claimed it out of curiosity.
Yeah. It's "free" in that I have to buy additional content from DNDB to get the stats I need to run the darn thing.
"Want to run this encounter with the fomorians? That'll be $30."
Have I mentioned how much I hate this a la carte shopping?

Most Adventurers assume you own the monster manual.

That said, it looks like the days of them selling stuff piecemeal in new content is over, so it's not something we'll have to worry about any more.

You can still get stuff piecemeal. The book has to come out first however.

I am not sure if it is still this way, but any book on could be purchased in pieces. He is snip from the Candlekeep Mysteries, see below. You can but just the monsters from the book for $9.99 or individual monsters for $1.99. You also have similar options for magic items. You can also buy all the books compendium content for only $19.99

If you bought the physical book it would direct you to the monster manual like all other 5e adventures. The Appendix only shows new monsters.
