Spellcasting - Player's Handbook (2014)
Spellcasting. Magic permeates the worlds of D&D and most often appears in the form of a spell. This chapter provides the rules for casting spells. Different character classes have distinctive ways of learning and preparing their spells, and monsters use spells in unique ways. Regardless of its source, a spell follows the rules here. What is a Spell? A spell is a discrete magical effect, a single shaping of the magical energies that suffuse the multiverse into a specific, limited expression. In casting a spell, a character carefully plucks at the invisible strands of raw magic suffusing the world, pins them in place in a particular pattern, sets them vibrating in a specific way, and then releases them to unleash the desired effect-in most cases, all in the span of seconds. Spells can be versatile tools, weapons, or protective wards. They can deal damage or undo it, impose or remove conditions (see appendix A), drain life energy away, and restore life to the dead.

Or they might someday be reinvented by a character who has amassed enough power and wisdom to do so. Spell Level Every spell has a level from 0 to 9. A spell's level is a general indicator of how powerful it is, with the lowly (but still impressive) magic missile at 1st level and the incredible time stop at 9th. Cantrips-simple but powerful spells that characters can cast almost by rote-are level 0. The higher a spell's level, the higher level a spellcaster must be to use that spell. Spell level and character level don't correspond directly. Typically, a character has to be at least 17th level, not 9th level, to cast a 9th-level spell. Known and Prepared Spells Before a spellcaster can use a spell, he or she must have the spell firmly fixed in mind, or must have acc...
