SP [Lizzie] build used with the [Temple] build linked here.
We will be using blast and toxin as the damage on this build so that Primary Blight will activate.
Toxin damage is used since the [Temple] build mentioned has [Archon Continuity], which adds corrosive status as well.
When used with your 3rd ability, Lizzie will have 5 total status effects on its primary fire - Heat, Toxin, Corrosive, Blast, and Slash due to [Hunter Munitions], all of which will contribute to [Galvanized Aptitude].
When aiming down sight, you'll want to shoot out the other status such as Viral, Magnetic, and Cold, and for some reason, it also applies Impact status.
Total 9 status effects which will help activate Arcane Impetus as mentioned in the [Temple] Build linked above.
Eventually when you get Arcane Hot Shot, you will want to replace [Critical Delay] with [Rifle Elementalist].
