Blood Tome (Japanese: 魔王の血書 Demon King's Blood Book) is a weapon skill in the green tome category which debuted in Fire Emblem Heroes; it is a personal weapon of the fallen variation of Lyon. When a foe uses a 2-range weapon, Blood Tome reduces the damage the foe deals with area-of-effect specials and regular attacks, and grants weapon triangle advantage against foes that are also colorless.
