Alternatives(remember to swap the banes based on the enemies you are fighting):

Electric (the one above):
Electric proc (status) scales with enemies grouped in the range of the proc. This means, that if you have 1 enemy, hit it with probocis, proc electric, it will only stun him. With 2 enemies, each enemy will get zapped (damaged) by the proc of the enemy next to him based on the base weapon dmg (modified via elec mods and base dmg). Lets say this makes the status proc do 2 damage. If we add a 3d enemy, the status proc would do 6 damage, if we add a 4th it would do 12 dmg, and so on. This is why its used in probocis, as it doesnt grow linearly, but more like exponentially. This is good against most enemies, but not as good for killing grineer.

raw tox (corpus):
Swap both of the elementals for tox. This is not recommended as the build above is better, but against a single target raw tox would be better.

Grineer build(heat/slash viral)
Swap the elec mods for 60 60 heat/[Fanged Fusillade] (for higher enemy lvl) and [Rifle Aptitude], swap the bane for grineer. This build would be better than the elec build on enemies that arent stacked or with armor strip.

Infested build (corroheat)
Swap elec for corro (60 60 tox and elec), and vig armaments for heat, so that the weapon ends up with corro and heat. Swap the bane for infested or just for vig armaments as infested are paper.

Gas(up to the user):
Swap both of the elec mods for 60/60 heat or tox and the other elec mod for 120 heat or tox (based on ur 1st choice to make gas). Gas also scales a bit like electric, but slower and weaker. This is from 6 to 8 times worse than raw elec, but some people just like gas.
