An alternate cover is available only in local game stores with art by Wylie Beckert. On the hidden elements within the alternate cover art, Beckert said, "My favorite thing to hide within the image was the spell Tasha’s hideous laughter. In the art brief, this was meant to be a scroll with identifying text on it. But I wanted to find a more subtle way to show it, hence the possessed scroll of laughing imps and skulls. The art brief also called for Graz’zt to be 'looking flirtatious'. I figured the flirtiest he could get would be offering Tasha a uniquely demonic valentine". The book features "in-character commentary from Tasha", as well as several new spells and magic items iconic of the character. The book also includes a "de-Eberroned" version of the group patron mechanic and of the artificer class and its subclasses, along with reprints of several subclasses that were previously published in other supplements for specific campaign settings: the Order Domain Cleric and Circle of Spores Druid from Guildmasters’ Guide to
