Exploration is an integral part of Genshin Impact and with Inazuma update, players have a lot of areas to explore. Inazuma is different from the existing areas in Liyue and Mondstat, it has some new mechanics which players need to be familiar with to make sure that players do not miss out on chests and collecting other materials. To aid travelers in their exploration of Inazuma, Genshin Impact developers have introduced Electrogranum. In this article, we will find out what electrogranum is and how to use it.
Like Dragonspine which has a lot of its interaction based on cryo, Inazuma is completely built around the electro element (Inazuma in Japanese means Lightning). Inazuma was an area that was isolated from the other islands because it was locked down under the Sakoku Decree meaning and hence this part of the world functions differently.
What is Electrogranum in Genshin Impact
Electrogranum (singular for Electrograna) is a grana that float around the traveler for 15 seconds (at level 1 and 2) and helps in traversing through Inazuma. A Grana is a curious spirit bursting with elemental magic that follows the player along. In mondstat there is anemograna. Collecting 3 anemograna creates a wind current. Electrograna is the grana for Inazuma and since Inazuma is the land of electro archon the grana is of the element electro.
How to activate Electrogranum and what does it do?
To activate an Electrogranum players will need to locate the Sakura Bough which is found abundantly throughout the three islands. On locating the tree players need to interact with it and then the Electrogranum will be summoned and will stay for 15 seconds (at levels 1 and 2). Electrogranum is used for various purposes as follows,
1. To activate Thunder Sphere
It is a traversal mechanism found in the skies of Inazuma. It is activated when players come in contact whilst being affected by Electro or if they have an Electrogranum with them. This mechanism is used in various puzzles and challenges (time trials) across Inazuma. Also, this mechanism is used in the event “Thunder Sojurn”.

2. To get past Thunder Barrier
There are three types of electro barriers, differing in terms of strength. Players can use the Electrogranum to get past these barriers as long as the level of electrograum is high enough.

3. Protection against Thunderstone
Some of the thunder barriers have thunder stones inside them which inflict electro damage over time. Players can temporarily avoid the damage if they have an Electrogranum by suppressing the thunderstone.
4. Protection against Balethunder
In some parts of Inazuma players gradually lose HP as these areas are highly concentrated by electro. This phenomenon is known as Balethunder and by using Electrogranum players can avoid damage by using Electrogranum.
How to level up Electrogranum in Genshin Impact
Located at the top of the Grand Narukami Shrine, the Sacred Sakura tree is a mesmerizing location that players will be visiting time and again for offering sigils in return for rewards.

Unlike Liyue and Mondstat where sigils are used to buy a variety of items from the Souvenir Shops, Inazuma uses the sigil to level up the Sacred Sakura tree. By offering the Electro Sigils to the Sacred Sakura tree, players increase their Favor Level.
