You will learn that witches use a variety of magic, from elemental magic to telekinesis. They also master various spells and can use any power, even those not inherent to them from birth, but they will not master it to the fullest extent of those who are given it from birth. For example, a witch who masters the power of wind and air can learn fire magic, but will not master it as well as a natural fire witch. Witches can also use various weapons, infusing them with centuries-old powers and magic: scythes, swords, magic wands, pendants, medallions. They can also use artifacts and stones. Many also use their hands. Magical clots in the form of balls appear in their hands, and then they use their powers. They summon wind, control water, or move objects with the power of thought, then their eyes glow in different colors. Purple, for example, means telekinesis. Blue means water. Gray means air. Red means fire. But if you use magic of a different element, the glow in the eyes doesn't change color, only the shade. For example, purple with a red or gray tint, but the base color remains the same. Also, the longer a witch lives, the greater her power and, consequently, the smarter she is. And the more varieties of spells and elemental magic she has mastered.
