@King Cosmos You can have that sword when the oppurtunity presents to get another unique artifact. Unless you want to take your current unique and make it common.
As for Zeroing Out. Will be added to the first post.
If you agree to a duel for instance where your artifacts are on the line you can lose them.
If you are on a quest, mission, whatever where you are the sole avatar involved everyone else is AI you lose nothing but the progress you made. You will lose cash & artifacts you gained during the quest since you failed to complete it.
If you are on Doom World or any other MOBA world, you will lose all your cash. If a clan mate can jump in and collect your cash before your vanquisher does you can get it back, if your clan mate is willing. Same thing if you are on a team battle not with your clan.
Because of things that will present themselves during the plot quest, will change the rules that I can’t reveal now. These will raise the stakes for everyone whether they are playing games like our avatars or just working for Sony as an office worker. No one is safe.
