The combination of fire-based prosthetic tools and oil is a potent strategy in Sekiro: Shadows Die Twice, capable of inflicting significant damage and creating devastating area-of-effect attacks. The Flame Vent prosthetic, when ited, deals continuous fire damage to enemies caught in its blast. However, its effectiveness is dramatically amplified when an enemy is first doused in oil. This can be achieved by using the Oil Jar consumable item. When an enemy is covered in oil, any subsequent application of fire, whether from the Flame Vent or even a well-timed sword strike that ites nearby flammable objects, will result in a much larger and more intense burst of flames. This combo is particularly effective against groups of enemies or against larger, more resilient foes who might otherwise take a long time to defeat. The visual spectacle of an oil-soaked enemy erupting in flames is matched by its tactical advantage, as it can quickly turn the tide of a difficult encounter.
To execute the fire and oil combo effectively, players must first acquire the Oil Jar consumable. These can be found throughout the world or purchased from merchants. Once an Oil Jar is thrown at an enemy, they will be coated in oil, indicated by a visual effect. Immediately following this, You should equip and deploy the Flame Vent prosthetic. The Flame Vent, when activated, will ite the oil, causing the enemy to take substantial and sustained fire damage. This combo is especially useful against enemies susceptible to burning, such as the Headless or certain types of corrupted soldiers found in areas like the Ashina Castle. The duration of the oil coating is limited, so swift execution after applying the oil is crucial. Furthermore, You can strategically use the environment; if an enemy is near a brazier or other flammable object, iting that object after applying oil can also trigger the fiery explosion. This tactic requires precise timing and positioning, but the payoff in terms of damage and enemy disruption is significant, making it a valuable addition to any shinobi's arsenal when facing tough opponents like the Blazing Bull.
