This build was made for [Gara]'s sweeping attack (Held 1), so i reccomend to invert settings so tapping [Gara]'s 1 does the sweeping attack, as the [Gram] is a high slash weapon with a lot of damage
([Gara]'s 1 is based on piercing damage and elements, while her held 1 is based on slash and elementals)

(you can replace [Jagged Edge] with [Carnis Mandible] if you have unmaxed mods, but i don't reccomend it, as this assumes you just want the [Gram] for [Gara]'s abilities, which will kill ennemies before the [Gram] can hit them with a few stacks)

i do not reccomend the [Gram Prime] if you want to use [Gara]'s Piercing attack, you should use the normal [Sydon], as it's the best weapon for piercing
(you should only do this if you don't have the [Gram Prime] or the [Galatine Prime], but you do you)

this build was made cause i don't have the [Galatine Prime] yet (it has more slash)
