Linley was thrilled. With hands still trembling, he took out the envelope pressed beneath the three grenades and opened it.
Inside was a handwritten letter from Teacher Green.

Their lethal radius after detonation was five to ten yards, and factoring in the distance their fragments could travel, their danger zone could even reach fifty yards!
Unlike wizards' spells, even when a wizard capable of silent Wandless Magic cast one, the light produced during its flight would still draw an enemy's attention and alert them.
