Boiling Oil is a technology in Age of Empires IV that can be researched at the Keep and Castle and any landmarks that act as such starting in the Castle Age. Once researched, these buildings and Stone Wall Towers gain a boiling oil attack against nearby units that deals 30 damage.
While technically Boiling Oil is available in the Castle Age, the Japanese cannot access it till the Imperial Age, since the building at which it is researched unlocks in the Imperial Age.
Unlike other projectile-adding technologies, this is NOT an emplacement. Hence, it is affected by bonuses that affect technology research speed and cost, and researching this once affects all buildings. It is also different from most other emplacements (except the Mangonel Emplacement) in that the projectile deals siege attack, instead of the ranged attack.
Civilization bonuses[]

- Byzantines: Research speeds are 30% faster per water level at buildings within the influence of a Cistern with the Dialecticus ability active.
