Community: Underdark Spell Components

There’s no convenience store selling crucial spell components when your back’s against the rock face in the Underdark. Could naturally occurring materials stand in for their above-ground counterparts?


On a good day, the Underdark is a labyrinth of mystery, madness, and macabre creatures. Few dare enter and even fewer return. Casting spells in the Underdark is also no easy feat and preparation is, of course, key.

Yet even the best adventurers sometimes forget to stock up on the essentials, and it’s no good rummaging through your bag of holding arguing over who was supposed to pick up the powdered opal and that live caterpillar as a horde of illithids bear down on you.

What if you could get around this problem using alternate material spell components that are plentiful in the Underdark? We asked you to swap an item not readily available in this harsh environment with one that would be. Here are our favorites…
