Navia is a Geo DMG dealer who can use Elemental Shards created from the Crystallize reaction to enhance her Elemental Skill.

When a character in the party obtains an Elemental Shard created from the Crystallize reactions or when Navia's Elemental Burst hits opponents, she will gain Crystal Shrapnel. Unleashing an Elemental Skill will consume all Crystal Shrapnel stacks and fire Rosula Shardshots, dealing explosive DMG to opponents.

Her Elemental Burst bombards opponents in front of her, dealing AoE Geo DMG, and will periodically bombard the area afterward.

This guide is based on the Community Character Builds by the Genshin Helper Team.

Skills Overview

Normal Attack: Blunt Refusal

Normal Attack
Performs up to 4 consecutive strikes.

Charged Attack
Drains Stamina over time to perform continuous spinning attacks against all nearby opponents.
At the end of the sequence, performs a more powerful slash.

Plunging Attack

Elemental Skill: Ceremonial Crystalshot

When a character in the party obtains an Elemental Shard created from the Crystallize reaction, Navia will gain 1 Crystal Shrapnel stack. Navia can have up to 6 stacks of Crystal Shrapnel at once. Each time Crystal Shrapnel gain is triggered, the duration of the Crystal Shrapnel stacks you already have will be reset.

When she fires, Navia will consume all Crystal Shrapnel stacks and open her elegant yet lethal Gunbrella, firing multiple Rosula Shardshots that can penetrate opponents, dealing Geo DMG to opponents hit.
When 0/1/2/3 or more stacks of Crystal Shrapnel are consumed, 5/7/9/11 Rosula Shardshots will be fired respectively. The more Rosula Shardshots that strike a single opponent, the greater the DMG dealt to them.
When all 11 Rosula Shardshots strike, 200% of the original amount of DMG is dealt.
In addition, when more than 3 stacks of Crystal Shrapnel are consumed, every stack consumed beyond those 3 will increase the DMG dealt by this Gunbrella attack by an additional 15%.

Hold
Enter Aiming Mode, continually collecting nearby Elemental Shards created by Crystallize reactions. When released, fire Rosula Shardshots with the same effect as when the skill is Tapped.

Talent Priorities

Skill > Burst = Normal Attack

Navia is a DPS that doesn't demand much field time. While most of her DPS is frontloaded into her Skill, she can stay on-field to take advantage of her 4s Geo conversion window. Her Burst lets her generate Crystal Shrapnel stacks and is important to use every rotation.
