My Sancti Tigris build.

It is designed as a purely slash weapon.
Thought process : Shotguns have innate multi-shot… So multi-shot mods, obviously. Multi-shot allows for multiple critical hits, so using [Hunter Munitions] was a choice for status effects, as using mods like [Sweeping Serration] don’t actually increase DAMAGE, but the Slash stat, requiring much more mods for what I thought would end up being a weaker and more complex result. Focusing on damage, using multiple mods to increase TOTAL damage seemed like a good idea for me.
Acceleration and Tainted allow for more pellets to hit the target, causing more damage and increasing its effective range while also increasing fall-off, allowing risk-ranged shots to be actually worth it. The default accuracy wasn’t that good for me, this fixes an issue I had while also making use of the slots’ innate polarities.
[Ravage] is for extra damage.

Slash status damage is based on total damage, from what I could tell so far.

I love this gun, can’t wait to fully level these mods and get [Primed Ravage].
