Used on Thunder Barriers

The Thunder Barrier is an impassable obstacle found in Inazuma, and is similar to the Wind Barriers found in Mondstadt. The only way to get through a Thunder Barrier is by having an Electrogranum!

Thunder Barrier Strength Levels

Thunder Barrier Levels
Level 1	Level 2	Level 3

The stronger a Thunder Barrier is, the stronger your Electrogranum should be! If you can't pass the stronger Thunder Barriers, then you'll need to raise your Electrograna level.

Defense against Thunderstones

Some Thunder Barriers contain Thunderstones within them that deal continuous damage to players within the barrier. Having an Electrograna can temporarily supress the Thunderstone so you don't take damage!

Used for Balethunder

Some areas in Inazuma are affected by high Electro concentrations that gradually drain your HP. This effect is called Balethunder and is similar to the Sheer Cold effect in Dragonspine. Players can use Electrograna to avoid taking damage from Balethunder!

Used to Solve Lightning Probe Puzzles

Lightning Probes point towards creatures, items and characters affected by Electro. You can use an Electrogranum to steer the Lightning Probe where you need it to point towards.

Relay Stone Substitutes

The new Electro Mechanism works similarly to a circuit. You can use Electrogranum as a substitute for Relay Stones to complete the circuit in Electro Stone Puzzles.
