There are many items, weapons and equipment in Naraka: Bladepoint. These are found by exploring the map and can be looted. Some of them are environmental elements that do not appear on the map and therefore can be difficult to find.
One of these items is Salak. This fruit can be found on short trees that are roughly the height of the character and can be recognized by their red color and the prompt that appears when the player is near it. Generally, these bushes can be found in settlements near buildings or by taller trees scattered throughout the map.

By consuming a Salak, the player will gain improved defense for 120 seconds. This can be useful when fighting another player as it will reduce damage taken. Unfortunately, the player is unable to pick up Sarka and place him in their inventory.
Once you consume a Salak, a blue aura will appear around your character. This lets you know that you are still benefiting from the buff provided by the fruit. Although Salak's buff cannot stack with other Salak, it can stack with other buffs from other environmental objects.
