there's lots of reasons this might happen. Can you give us more details?
I'm really not sure what to say! While going about my daily items, at the very least once a day, I'm finding a Blue Arm Cast in my inventory. I'm not sure if it's just a common random event that I always miss or what is going on. It's very strange!
That does seem a bit odd. They are sold in the Medicontra shop and are pretty cheap in user shops. I don't think that any quests would give them out though, since they're artifact rarity. Do you vend at all? Maybe Ocean Depths gives them out, since "blue" is one of the keywords for that vending machine?
Oh wait! If you frag your items every day then it might not be a new item every day. It could just be the same one that never left your inventory because Artifact rarity items can't be fragged.
yeah see, what said. If you don't stuff it into your shop or donate/destroy it then the very same item won't go from your Inventory and they will slowly accumulate. Or, if you quest, you could get it. Or someone could be giving them to you and you are not noticing the Event. Or since it's blue and several machines vend on 'blue' you could get it multiple times as the way Subeta is going there is not an even distribution of low rarity items, but Vending has a rarity cap so the same items will show up again and again. Or you could be double clicking when you buy from usershops to do a quest and getting one more copy than you need. Or karma could be warning you that you're about to break your arm.
Oh I bet that's it then! I thought all cheap items could be fragged. And I do sometimes frag multiple times a day so that makes total sense. I feel really silly now /blush
I'm pretty sure Laurey gave me the correct answer but thank you for the follow up information. I think I'll destroy the blue arm cast as a way of telling karma to gtfo.
