[RPG] Which spells are hidden in adventures and other sources


When it comes to spells in D&D 5e, I had a very good overview. It's not like with subraces or feats, for example, which are scattered across a multitude of official and less official sources. The number of spells is quite manageable, as they are all contained in the Player's Handbook, the Sword Coast Adventurer's Guide, the Elemental Evil Player's Companion, Xanathar's Guide to Everything, and that one Unearthed Arcana article (UA: Starter Spells).

…Or so I thought.

Then I stumbled over Flock of Familiars, a 2nd-level conjuration spell that lets you summon three familiars at once. This spell appears in Lost Laboratory of Kwalish, an adventure officially published by WotC.

That made me wonder:
Which spells are hidden in adventures and other sources?

Best Answer

Only 10 spells.

A careful query on D&D Beyond shows three spells from the Lost Laboratory of Kwalish adventure, for warlocks and wizards:

And an additional 7 from Acquisitions Incorporated, a book that contains an adventure in it. As time progresses, you may need to update the filters in the query.
