The Filter is Designed to Highlight Early Links / gear. This one Focuses on Arm & Arm/Es | Later on in the Campaign it Hides Equipment we won't normally use such as weapons like Bows/Swords etc. You should pick up Early Gear to sell so you can get transmutations to craft fire resistance in Act 2.

This filter will hide a lot more equipment. This will also hide the new top tier bases that are not pure armour. Red outline = T1 = Best Base Orange Outline = T2 = Second Best kind of Yellow Outline = T3 = not as good base
