So the full build I was using was:
All Pursuit Paradox shotgun with T4 Swamp Wood handle (firing Ice) made with Forge minor card and crit, ranged damage and magick infusions
Humbaba Explorer's hat (didn't have enough Jana when I made it but makes no difference for damage) with ranged damage, crit and melee infusions. Could possibly get a marginal bit more swapping the melee for magick but probably little in it
Hermetic's Humbaba Formal Shirt and Desert Fibre Boots both with Magick infusions. Possibly more damage available using T3 Fabled Carnute but didn't have any when I made them. Think the shirt had Fingernail buttons.
T3 Carnute (not fabled) Calcularian gloves with ranged damage, crit and melee infusions (again possibly a tad more with a magick infusion)
Running the following Charms - Spellsword, Patience, Sniper, Venom, Called Shots, Blindside, Morale
Casting Assasin's Sight
Eating (drinking) 3 Nectars (all with slightly different ingredients). This is done after eating some meat with the Herbivore Charm on my Spyglass to enable the Venom charm to work
And finally using the Duelist Minor Realm card
I think I got everything - kept on forgetting steps when I was making the runs. Oh yeah, I mostly clapped
