The Tomb of Annihilation is a popular Dungeons and Dragons adventure game set in the Forgotten Realms. In this game, the players are tasked with exploring the titular Tomb, a dangerous and mysterious ruin. One of the most difficult challenges to complete in the game is the Hex Foundry, a hidden chamber full of traps and puzzles. To make sure your party survives the Hex Foundry, it’s important to know how to hide it. Here are some tips on how to hide the Hex Foundry in Tomb of Annihilation.

Choose the Right Location

The first step in hiding the Hex Foundry is to choose the right location. You want to make sure it’s in a place that’s difficult to find, but not impossible. Pick an area that’s not too close to the entrance of the Tomb, and one that’s away from the main paths and areas of exploration. This will make it harder for players to stumble across the Foundry accidentally. You also want to make sure that the area is large enough to hide the Foundry’s entrance.

Hide the Entrance

Once you’ve chosen a location for the Foundry, it’s important to make sure the entrance is hidden. There are several ways to do this. You can cover the entrance with a large stone, or you can use illusion magic to make the entrance appear to be something else. You can also create a false wall or secret door to further conceal the Foundry’s entrance.

Set Traps to Keep Intruders Out

In addition to hiding the entrance, you should also set traps and other obstacles to keep intruders out. You can use magical traps, such as fireballs and lightning bolts, to deter players from entering the Foundry. You can also use physical traps, such as pits and tripwires, to make it difficult for players to progress.

Use Magic to Conceal the Foundry

You can also use magic to conceal the Foundry. Illusion spells are a great way to make the entrance appear to be something else, such as a mundane wall or door. You can also use divination spells to detect if the Foundry is being observed or if any creatures are nearby. This will give you time to prepare and hide the Foundry if needed.

Hide the Contents of the Foundry

The last step in hiding the Hex Foundry is to make sure the contents are hidden as well. You can use spells such as Nystul’s Magic Aura to make the contents appear to be something else, such as mundane objects or items. You can also use traps and wards to keep the contents safe and secure.


Hiding the Hex Foundry in Tomb of Annihilation is no easy task, but with the right tactics, it can be done. By choosing the right location, concealing the entrance, setting traps, and using magic to hide the contents, you can make sure that the Foundry remains hidden from prying eyes. With these tips, you’ll be able to keep your party safe and make sure the Foundry remains hidden for years to come.
