Later this week EN5ider releases its 500th issue, a megadungeon guided by our patrons and designed by over a dozen of our best writers: the Vault of Splintered Souls!

Update: The Vault of Splintered Souls MEGADUNGEON is now available!
Anyone that follows me on Mastodon may have spotted some early previews of the megadungeon and playtesting snapshots, and there was also a Q&A on the Random Worlds chatroom, but we've got a few extras yet. For example the map above is an alternate for Level 4: Kotaur's Charge by Anthony Alipio. We ultimately used something simpler (and have advice on hand-drawing a map so GMs playing in person don't have a stroke
) but for the most thorough groups of adventurers we figured this might be of interest.
Speaking of cohesive fun designs, Anthony's level is excellent. In addition to hitting the central themes (you'll see Kotaur himself on the cover soon!) he wanted to have a delve with nostalgia for Gauntlet, the party exploring a labyrinth in search of secret keys to progress forward. He did not stop there however, and there's some Marble Madness love too with a rolling sphere because the level tilts the further onward the PCs get. A little GM tool is used to keep track of the tilt so no worries there, and of course when everything's suddenly on a 20° incline the pit traps and ooze fights get a touch more exciting!
If you are not already a member of EN5ider you are simply missing out. There are 5 new articles each month (including an adventure!), we are about to have an archive of 500 articles, and you can access them all as soon as you're a member (which can be as cheap as $5 a month).

Dungeon Design
Regular readers may remember that this megadungeon was built using guidance from surveys (like this one) which determined overall themes: ancient, reactive, uses a deck of cards, and a classic feel. Everyone nailed it—each floor of the dungeon fits with the rest while being distinct with its own cool thing going on. The action-filled logic puzzle of the Crusher on level 2, the strange effects of level 6's Weeping Lady, the amplifying battles around the Soul Engine on level 8, and all the rest are beautiful episodes in the greater epic that is the Vault of Splintered Souls (with plenty of interconnected bits [the Aqualevel! ♥♥♥], soulshards aside).Speaking of cohesive fun designs, Anthony's level is excellent.

Soulshards and Soulsheets
One of the dungeon's reactive elements are soulshards, little nail-sized bits of magic that appear in the party's pockets after they leave (most) rooms in the megadungeon. They each have their own little benefit (recharging the use of class features, gaining temporary hit points, a burst of speed or regained spell slot, ending a condition, dealing extra weapon damage) in addition to a variety of unique uses in various levels, and dispensing knowledge from and about the dungeon. Maybe the most rewarding part about soulshards is how they set up pacing for dungeon exploration; as a GM you quickly get into a habit of seeing how many to roll for, and when you forget the party is quick to ask whether they find more on their persons (and not a room goes unexplored!) Our layout artist Frank did an excellent job making this tool more legible and usable, and I look forward to having it on hand whenever I run this again (rather than my admittedly messy tally sheet).A Final Preview
