Hey, I’m trying to farm gear on my main character on behalf of my other character.
When trying to equip gear my main farmed I got a “You are not a member of the required faction for this item”, when Iøm a me,mber of Circle of fortune.
An example would be Peak of the mountain, which requires lvl 12, but has the purple icon with rank 5 next to it.
I’m required to be part of the Merchant’s guild in order to trade and equip gear between my own characters??
No, your character that wants to wear items that another character got through Circle of Fortune mechanics is required to be a member of Circle of Fortune. And it’s not.
Purple icon means that it’s a CoF item. It seems like your second character hasn’t joined any of the factions yet, or joined MG instead. If it’s the first one, you can go to the first town and join CoF there.
Thanks! Hadn’t joined the faction yet, just did it and now I can equip the gear 
Thanks m8! Just joined the guild and now I can equip the gear!
