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%.
