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.

The filter is designed for highlighting good base items. It works for RF Chief & Elementalist. I will usually swap off this filter when entering maps
