Build and Runes
His Duskbringer can be seen in the fog of war, so if you think he is doing objectives such as dragon or baron, look for his Duskbringer particle.
Nocturne’s fear-leash can be broken when it goes out of range, so it’s best to save your jump abilities until he uses it.
Try to stay close to each other when Nocturne casts his ultimate, so that you’re able to react accordingly.
His spell shield only lasts for 1.5 seconds. Save your main damage abilities or crowd control for after it ends.
