Armsthrift

Armsthrift is a skill introduced in Fire Emblem Awakening.

Fire Emblem Awakening
When the user attacks or retaliates, this skill has a chance to activate, when it does, the weapon's durability will not reduce. The activation percentage is double that character's luck stat (including bonuses from a weapon, pair up, tonic or rally) thus, if the character's luck is 50 or higher, the weapons they wield will never degrade. Armsthrift is learned by Mercenaries at Level 1.
