Synapse is the perfect weapon for the farm Liches/Sisters. Of course, you can use it on other modes, especially aimed at killing a single target. As an application option - a steel path, but exclusively for killing a stalker. You can kill mobs, for example, with a glaive, but no one limits you - when using the full potential of the [Synapse], it will work very well against any goals.

Before the murder itself, you will have to bring all the galvanized mods and arcane to full power. About 5 kills per head will be enough for this. Arcane will add 360% damage, galvanized chamber 230% multi-shot, and galvanized sight 320% chance of a critical hit. YOU MUST DEFINITELY USE THE SIGHT, otherwise the galvanized sight and [Bladed Rounds] will not work. [Bladed Rounds] adds 120% critical damage, making [Synapse] an even scarier killing machine.

Since the [Synapse] has a synergy with riven mods equal to 5, it will be useful to use riven mod.
If you want to use riven mod, you can replace [Heavy Caliber] with it. The most important thing in your riven mod is to have critical damage. In addition to it, it will be nice to have a multi-shot or pure damage. (The chance of a critical hit is not needed, because the Synapse gives out red crits without it)

If you don't have enough ammo, use a Mutator/[Vigilante Supplies]. Also for increased rate of fire I use Arcane Acceleration.
