Only advice I will offer at this stage to you, do underwater, YOU look it up and learn. then you will get legendary artifacts that will crap all over that junk collar
I was planning to try my luck in Ararat when I came back (I suppose this is what u meant for underwater)
was killing stuff around the boat, discovering the zone.. then i've seen those 10 multi-bots going in.. So I just went out.. I would only go back to steal stuff and multiple time i've spotted the same 10 multi-bots.. the same 10 dude i'Ve spotted farming oni 24/7 8 days straight for splintering weapon.. reported them everytime.. I assume this was THE spot if u don't wanna pay for free stuff; ToL to do roof battle.
I had the feeling those 10 bots only took break from Ararat to farm splintering weapon somehwere.. So i decided to just wait on one of those event.. big mistake.
The quest to gain access was fun tho.. the only part I was like WTF is that poo poo was the destard dragon.. I had to multi account his ass.. everytime it's close to die; it would perch outside the map

PS: for Popps.. he got a point.. why the replica ain't coming back as heresy during those events.. like other items does.. why BS do not consider the minax invasion event as they consider the rest of those event; the non minax one?
If he would ask for some replica to come back as heresy (just look my LT sash.. it came back as an artifact from blackthorn dungeon later on)
Why not the gladiator collar? You know.. if he'd ask for that it would make WAY more sense than asking for the replica to be reworked.. would still be an heresy.. but this is in line from what we seeing (look the ninja earring for example)
Having a replica version does not justify not having a heresy one (mainstreaming something OP that was very rare, one of the worst way possible on a sandbox, limited time, shardbound and highly botted as a bribe)
At least, for my LT sash after the replica wich i give no damn.. the blackthorn dungeon one.. was real content u know.. not just a temporary bribe type of stuff meant to be botted... was still heavily botted (wich explain why everyone is being punish) but at this point this is a major BS issue since a decade, so nothing new..
