There are a number of special items and collectibles that you can find while exploring all nine realms in God of War: Ragnarok. You can find them to either unlock achievements/trophies that lead to a 100-percent completion playthrough or to make yourself stronger in the game.
Yggdrasil’s Dews are blue sacks hanging from tree branches over the water. Hence, the only way for you to find and pick them is by using a boat.
Yggdrasil Dews are incredibly important. They permanently increase your stats by +2 in the game, which in turn makes Kratos even stronger against the Berserks, Thor, and also Odin.
The following guide will tell you the locations of all Yggdrasil Dew in God of War: Ragnarok. Most of them can be found in the Bay of Bounty and the River Delta.
