In this video, I showcase a more min-maxed PURE item rarity magic find Tornado Shot Deadeye. I created this build due to not wanting to go the typical Quantity Gear route because these builds are extremely squishy due to requiring multiple items missing HP/Resistances and requiring the use of Petrified Blood + Divination Distillate, which makes you glass.
The reason Quantity gear isn't "required" for magic finding is because Rarity/Quantity on gear is additive to map Rarity/Quantity. Thus you can look at the rough math below that shows the currency per hour should be at most 30% less loot when comparing 80% Quant to 0% Quant, but I would argue that the increase in tankiness and quality of life stats that comes with a Pure Rarity build allows you to die less and run harder maps, thus roughly makes up for this difference.
8 Mod Map + Gilded Reliquary Scarab + God-Touch Average: (Rough Estimate)
0/0 MF = T1 Currency x4
0/600 MF = T1 Currency x12
80/600 MF = T1 Currency x16
(Character Rarity/Quant + Map Rarity/Quant) x (Party Size Bonus + League Mechanic Bonus) = Loot
Full Quantity Stats: (1 Mirror Budget)
Quantity: 80 Gear + 150 Map = 230 Total
Rarity: 600 Gear + 100 Map = 700 Total
DPS: 9.8 Mil + HH
Defense: 4-9k Max Hit + HH
QoL: None + HH
Full Rarity Stats: (1 Mirror Budget)
Quantity: 0 Gear + 150 Map = 150 Total (34% Less)
Rarity: 630 Gear + 100 Map = 730 Total (4% More)
DPS: 12.4 Mil
Defense: 6-29k Max Hit
QoL: Stun Immune, CB Immune, Ailment Immune, Curse Immune, No Mana Cost
Final Note: If you are in a group with an aura support, have an unlimited budget, or have legacy quantity gear in Standard, Quantity gear is likely marginally better.
