Fanaticism is a technology in Age of Empires that can be researched at the Temple once the Iron Age is reached. It increases the recharge rate of all Priests by 50%, allowing them to convert more units over shorter periods of time. Researching Fanaticism also allows the player to upgrade the Long Swordsmen to Legions.
