Bone Mail is a powerful armor and can be bought during the last Chapter in Baron for 37,500 gil. It provides 18 Defense, 72 Magic Defense, 1% Magic Evasion, -10% Evasion, and prevents Poison. It also strengthens defense against attacks from undead enemies.
- "Armor fit for a corpse!"
Bone Mail is the strongest armor in the game, defensively speaking. It provides a whopping 30 Defense, +10 more than Vishnu Vest, as well as making the user immune to instant death, Poison, Blind, Old, Confuse, and Berserk, and absorbing the Poison element and halving Ice-elemental attacks. However, the downside to equipping the armor is that the user is also immune to Regen as well as being weak to Fire and Holy-elemental attacks, giving -5 Stamina, and once the user is KOed in battle, they cannot be revived during the fight. Therefore it is advised to equip the Bone Mail with caution.
