of magic types. Arcane magic These are typically spells devoted to manipulating energy, converting one substance to another, or calling on the services of other creatures. Under the Vancian magic system, wizards would have access to spells that were committed to memory after a session of meditation upon a spellbook containing the details of the incantation. Once prepared, the spell is cast using specific words and/or gestures, and sometimes a specific material component; but the act of casting the spell causes it to fade from the wizard's memory, so that they cannot cast it again without first re-memorizing it. As the 3rd edition moved away from the Vancian magic system, some arcane spellcasters, such as sorcerers and bards, just knew their spells innately. Sorcerers are innate casters whose magic is influenced by the origin of their arcane connection. "Some sorcerers trace their magic back to a powerful ancestor, like a dragon, a celestial, or a djinni. Others can delineate their magic to an extraplanar source, such as the shrouded lands of the Shadowfell, or the roiling chaos of Limbo". This origin adds both thematic and mechanical constraints on the types of spells a sorcerer can learn. Bards have access to both destructive and healing spells. The healing aspect is "influenced by Irish mythology" where bards use "music and storytelling to weave together this magic to restore vigor and health to other people". Arcane power can also be accessed by more martial classes in the form of specific subclasses such as the arcane trickster and the eldritch knight in 5th edition. Divine magic Divine spells take their name from the fact that they are mainly granted to clerics by the grace of the cleric's patron deity, although the spells cast by druids, rangers and paladins also come under this category. Divine spells do not need to be prepared from a spell book. These spells are generally less overtly powerful than arcane spells and have fewer offensive applications. Cleric spells are typically devoted to either healing the wounded, restoring lost abilities, and acquiring blessings, or to inflict harm and to curse opponents. These spells must be prepared by the caster daily through a session of meditation or prayer. Clerics also have the ability either to turn (drive off or destroy) or to rebuke (cow or command) undead, based on their alignment. The spells and abilities of a cleric are based on their
