A cantrip is a simple spell in fantasy role-playing games, particularly in the context of Dungeons & Dragons. Cantrips are often low-level spells that can be cast without expending resources, making them useful for characters to use frequently. They typically have minor effects, such as creating light, producing sounds, or causing small amounts of damage. In many games, cantrips are available to all spellcasters, including wizards, sorcerers, and clerics. Unlike higher-level spells, cantrips do not require spell slots, allowing players to use them as often as needed. This makes cantrips a versatile tool for both combat and non-combat situations.
