i160 GEAR

These are obtained from level 60 dungeons "Neverreap" and "The Fractal Continuum". Bosses and treasure chests drop tons of ilvl 160 gear. These dungeons require ilvl 145* to enter.

*You can buy ilvl 145 weapons and armor pieces at the Goblin Trader, Idyllshire (7,6), to bump up your ilvl. They're pretty expensive though.. also the Goblin Trader doesn't sell accessories so you might need to farm some in "The Great Grubal Library" dungeon or do leves**.

"When you do leves you sometimes get an item called Amber-encased vilekin. I think I got 5 from an coffer of one of those leves that cost 10 allowance. Next to the levequest NPC in Ishgard there is an NPC called Amber Trader. This NPC trades ilvl NQ 145 accessories per 5 Ambers. NPC Location is at Foundation (10,10)." - Varius Gray (Thanks Varius!)
