You can buy Xanathar's Guide to Everything right here.
Almost done with this adventure! This is the 4th mission in Over the Edge, the Tomb of Annihilation Adventurer's League module that you can run in a game store. I think it will be on the DM's Guild in October.
This time we're checking out a tower. Soggy Wren says, "I walk with Those Who Harp..." which I find amusing. He asks the group to find the corpses of Harpers who went to the tower and never returned. He wants the heroes to find them and bring them back.
The tower is made of black marble. Everything else around it is covered in vines, but the tower is not. There is seemingly no entrance. There are runes at the base of the tower.
What follows is a very cool puzzle. All of these adventures have unique, good ideas in them. This definitely something a lot of people could steal and use for their home game.
Once the group gets in, they find out that there are creatures inside! There is a battle involving ranged attacks and barricades, which sounds fun.
Then there's an encounter with a type of naga. The floor is charged with energy - you can step on certain areas to harm creatures standing in other areas. Awesome.
There's a very cool twist that I won't reveal, but make sure you read the whole thing so you can foreshadow it if it seems fitting to do so.
This is a higher level adventure, so there's a big pile of gold (3,000 gp), a spellbook and 3 scrolls.
Looking at the treasure... we're back to "This item can be found in the Dungeon Master's Guide." We flew too high, my friends. We got burned by the sun.
Good adventure! Very short, but I bet it will fill an hour or more at many tables, which is the goal.
Only one mission left! Something about an altar..
