In the original PlayStation 2 version, it provides 24 Attack, 6 Evade, +35 MP, +3 Magick Power, 33 CT, grants Faith to a target at a 60% chance, requires the Rod of Faith License to equip, and has the same damage formula as guns and measures. It can be obtained on Mt Bur-Omisace after completing the Behemoth King Hunt.

In the Zodiac versions, it now provides 21 Attack, 6 Evade, +6 Magick Power, 33 CT, has a 60% chance of granting Faith to a target, and requires the Rod of Faith license for 130 LP. It can be found as a treasure in Cerobi Steppe (The Terraced Bank), in Mt Bur-Omisace after the Behemoth King hunt, and is uncommonly stolen from Exodus in Trial Mode Stage 68.

Final Fantasy Tactics

The rod of faith provides 5 attack, 20% weapon defense, granting Faith status to the user while equipped, and bestowing Faith to the target when attacking with it. It can be found as a rare treasure in Midlight's Deep (VALKYRIES). It can be considered the ultimate rod of Final Fantasy Tactics, though rods remain weak if used for physical attacks.
