How to get 100% exploration in Genshin Impact 4.2 maps: Priorities, quests, waypoints, and collectibles list

HoYoverse released two areas in the ongoing Genshin Impact version 4.2 update, namely the Erinnyes Forest and Morte Region. Both regions are fairly large and cover around one-fourth of the entire Fontaine map. Naturally, there are a ton of chests, Hydroculus, Foggy Forest Branches, and other collectibles that travelers can collect while exploring the new areas to get a 100% exploration rate.

However, several other items are hidden. This can prevent players from getting a full exploration rate, which can be slightly annoying. This article lists all the items you can get in Genshin Impact 4.2 and 100% in Morte Region and Erinnyes Forest.

Genshin Impact 4.2: How to get 100% exploration in Erinnyes Forest and Morte Region

Priorities

To get 100% in the Morte Region and Erinnyes Forest, it is necessary to unlock the entire map and have access to all the locations. Luckily, most of the areas are accessible from the beginning. However, two locations in particular cannot be accessed without completing their associated quests, and they are:

• Roots of Erinnyes.
• A hidden cave near The Rusty Rudder.

To get to the Roots of Erinnyes, you must complete The Wild Fairy of Erinnyes World Quest in Genshin Impact. Doing so will also unlock a secret location below the Marcotte Station, where you can find a hidden teleport waypoint, Hydroculus, and a few chests.

For the cave near The Rusty Rudder, you need to do a hidden mission in this location. Talk to Permingeat on the shipwreck and operate the cannon to break the rock and open the cave entrance, where you will find another hidden teleport waypoint. In addition, this is one of the prerequisites to obtain all the chests and Hydroculus in the new version 4.2 Fontaine map.
