Ivaldi

Ivaldi is the Sacred Twin Light Magic tome in Fire Emblem: The Sacred Stones. Like most other Sacred Twins, its might is doubled when used to attack monsters, however if a Bishop uses it to attack a monster, a glitch will make the Ivaldi's double bonus overwrite Slayer's triple. This fact makes some players preferring to equip the Aura for a Bishop, as its 15 power will be tripled becoming 45, but Ivaldi's 17 will become 34 instead. There's a drawback; the tome is heavy, and will slow the wielder down.
