Gara releases a slowly expanding ring of molten glass, which expands outward and downward, creating a wall of glass around her. This occurs over 3 seconds, during which Gara is invulnerable. This ring expands to 11m base at max rank. While expanding, enemies that come in contact with the expanding wall become encased in glass, which hardens around them, crystallizing them for a Duration – during this time, they lose resistance to Weapon Damage.
The glass wall itself, which hardens when it reaches maximum Range when Gara runs out of Energy, or upon recasting, consists of 12 panels, each with 2,225 base Health, which is further augmented by Gara’s Armor stat. When a panel is destroyed, it shatters causing Damage to all enemies within Range. Gara can recast the Ability to shatter all panels. Note that although players can move through the glass wall without issue, you can also perform wall grab and jumping maneuvers off it.
Gara can use her Shattered Lash Ability on a glass panel to instantly destroy it, inflicting both the Shattered Lash Damage plus additional Damage from the shattering of the panel. In addition, casting Mass Virtify while Splinter Storm is active will refresh the Duration of this Ability and its effects.
So, all things considered, here are some builds you may want to try on your Gara:
