Hi everyone, 

the spell "Irresistible Dance" is nowhere to be found on D&D Beyondis available with. The spell is available in the SRD OGL v5.1 (https://media.wizards.com/2016/downloads/DND/SRD-OGL_V5.1.pdf). Instead, a spell called "Otto's Irresistible Dance" with the same spell contents is made available in the Basic Rules which I believe should be classified as a spell from the Player's Handbook.

The SRD spell is specified as follows:

Irresistible Dance

6th-level enchantment
Casting Time: 1 action 
Range: 30 feet 
Components: V
Duration: Concentration, up to 1 minute 

Choose one creature that you can see within range. The target begins a comic dance in place: shuffling, tapping its feet, and capering for the duration. Creatures that can’t be charmed are immune to this spell.

A dancing creature must use all its movement to dance without leaving its space and has disadvantage on Dexterity saving throws and attack rolls. While the target is affected by this spell, other creatures have advantage on attack rolls against it. As an action, a dancing creature makes a Wisdom saving throw to regain control of itself. On a successful save, the spell ends.

It would be great if you could add it to the Basic Rules-set of spells. Thanks!

Keep in mind that the “Basic Rules” as it is called here is actually a combination of the Basic Rules pdf from WOTC and the SRD.  Both are free from WOTC.  While the SRD uses “irresistible Dance,” the “Basic Rules” pdf actually uses the name “Otto’s Irresistible Dance.” DDB opted to use the Basic Rules name, not the SRD name.

Thanks, I learning something today. I thought Basic Rules was just a fancy name for SRD, but it's obviously more.
