One aspect of Dungeons & Dragons 5th Edition that I like is the idea of wild magic areas. However, I don’t like wild magic effects tables that focus on effects that only last a few combat rounds, and I really don’t like ones that have a lot of positive effects, especially healing, which is part of the cleric’s domain.

So I created my own wild magic effects tables focused on what can happen in a wild magic area when magic is used, the effects of which are nearly always bad, and which tend to last for days.

But also, I wanted wild magic effects to occur when a spellcaster is working with magic in unusual ways, such as creating a magic item or new spell or mixing magic together in unpredictable ways (drinking multiple potions at once, for example). Because of this, I wanted such experimentation to be more flavorful by mimicking the traditional vignette of a lone wizard or witch performing magic in an isolated location under the light of a full moon.

In the material below, I use “sorcerer” to refer to all users of arcane magic. In my world, wild magic doesn’t affect clerics, because their magic comes from a different plane than that of sorcery.

Wild Magic Areas

Some areas of the world are crossover points where the “seams” of the Material plane and that of the Ethereal plan cross or are areas that have worn thin between the planes. In these places, often quite small, the casting of spells and use of other magic can cause strange effects.

Magic that is affected includes sorcerer’s spells, creature’s spell-like powers, spells from magic items (a staff, wand, etc.), the use of the powers of magic items (boots of speed being used for their speed, for example), the drinking of potions (but not tonics), and the reading of scrolls. It does not include the bonuses of magic weapons and armor or the mere presence of magic items, nor does it include any holy or sacred items or the performing of rites (clerical spells).

Each time magic is used in the area, perform a skill check to determine if the magic works normally or (on a failure), the caster suffers a minor wild magic effect.

Be sure to read the effect first and decide how to relay it to the player. Some effects will not be obvious immediately. Effects are considered a curse and can be lifted as one. For some effects, the GM may rule the character is allowed a saving throw.

• “Full moon” means the effect lasts until the character is touched by the light of the full moon. If the effect occurs while the character is under a full moon, the effect lasts until dawn.
• “Two full moons” means the effect lasts until the character is touched by the light of the full moon after the next full moon. If the effect occurs while the character is under a full moon, the effect lasts until only the next full moon.
• “Dawn” means the effect lasts until the character is touched by the light of the first hour of dawn.
