Spellcasters are individuals who use magic to perform various supernatural feats. They often draw upon mystical energies or forces to cast spells, which can produce a wide range of effects, from healing to summoning creatures. Common types of spellcasters include wizards, sorcerers, and witches, each with their own unique methods and sources of power. In many stories and games, spellcasters require specific tools or components, such as spellbooks or magical artifacts, to enhance their abilities. They may also have to follow certain rules or rituals to successfully cast spells, making their practice both an art and a science.
