GW2 Sunken Treasure Hunter Achievement Guide

GW2 Sunken Treasure Hunter achievement guide with locations of the Master Diver chests.[toc]

Getting Started


Go to Lion’s Arch and talk to the new NPC. She will give you an Ornate Rust Key if you ask her for it. This key will open any of the Master Diver chests. .


She also sell swim speed infusions and new ascended masks with the +10 swim speed infusions you can loot from the Master Diver chests


Getting Keys

The only additional way to obtain another Ornate Rust key currently is by completing a daily achievement to kill 10 kraits per day.


There are reports of random key drops off killing mobs (i.e.kraits) but that hasn’t been verified yet.

Master Diver Achievements


There are 10 Sunken chests located in 10 maps. You can use your Ornate Rust key to open one. Since you get a key/day, this may take a couple days to complete.

You get the title Freebooter and 5x +10 infusions to completing the Master Diver achievement. It is also a repeatable achievement you can repeat 10 times for 50 AP.


Each chest drop 3-4 +10 swim infusions and some greens. They also spawn a Veteran Krait Treasure Hunter when you open the chest.

Yes, the southern part of the EBG map, where the krait are constantly attacking the hylek mercenaries.

I can best that! I opened one yesterday, got none.
Confirmed by me, the even unluckier person 😛

i heard from someone that got a key in wvw.. are there still krait to kill in wvw?

Can confirm I got a drop from WvW. I ran past the hylek/krait camp in EBG tagged some of the mobs and got a drop.

It’s at least 2-4 +10 swim infusions, because I got 2 from one chest and 4 from a different one, also a friend just told me he got no infusions from a chest. So I would adjust that.

I suppose nobody has the new diving masks yet, but if/when someone does, can you confirm if unlocking the weight for one mask unlocks it for all three?

Confirmed from a guildie that buying one aquabreather DOES unlock it for all 3 weights. 🙂

these infusions are they for the new masks only ?

If no.. why would i sacrifice agony resistance for swim speed?

They only fit in Ascended aquabreathers, yes. As to why… The only underwater T4 Fractal is 76, for which you need 107 AR. Even if you didn’t put any agony infusions on your aquabreather whatsoever, if you have 150 AR from elsewhere chances are you’d still have plenty to spare.

there are 18 infusion slots, if you fit +9 in each slot you have 162 AR, if you sacrifice aquabreather, you still are overcapped

I agree with you too. It’s basically a resized version of the Bubble glider that’s been fitted over the head. 😛 I suppose that having to stretch it to fit over Charr heads would have been too time-consuming though, so this was the most expedient solution.

Hey Dulfy i have to correct you. They don’t drop 3-4 they drop 2- at least because i got 2 and not 3 out of my first one. 🙂

I received 2 on the free key, and 2 on the “krait earned” key. So the “drops” are at least a minimum of 2, not 3.

From late patch notes: “Rumors have surfaced about a mysterious Mists traveler.”
This line intrigues me, anyone know anything about that?

It seems it has something to do with an NPC. Possibly offering recipes to craft the Revenant weapons that were only available during beta testing of the HoT expansion.

From the looks of things, they finally made those weapons available, but so far not much info has been found on them yet.

The wiki shows a crafting recipe for the axe, but the other 2 weapons still have no new info on the wiki.
The recipes for the axe have no indication of how you get them exactly. I’m guessing this “Mists Traveler” has to be found and probably sells the recipes.

Hopefully, when people figure out what is needed to craft these weapons, Dulfy can have a guide for it so we know where to get the recipes and anything else that is needed to craft them.

7 days in, i’ve got 40 +10’s and completed the cheevo. After getting the cheeve everything else is a waste of time. But, I’ll wait n c what the next LW has if anything to do with this.

To get all 50 achi points=10 [chests]/1 [key/day]*10 [times to repeat the achi]-1 [free key, only once per account]=99 days

DD is correct if you need ALL possible AP from event, if you did not count random drop for keys from mobs, its 10 days repeated 10 times for 50 points, so well, if you play for 6 yers, 99 days is literally nothing (have you beer brew backpack ?? )

I seem to only be able to open any single Chest once – I opened the one in Sparkfly Fen yesterday, and could not open it today, so went to another one, and opened that fine.

I presume that I have to open all 10 separately and then the Acheive resets. Any ideas on this?

Only the first key opens up any chest from what I gather. The woman will tell you which chest gets unlocked from which key

I hope after doing all ten you can just go back to the same chest day after day. I am having the same problem.

better do it one time for me. I ll not spend 99 days on that and i can easily get an ascended breather from bitterfrost farming 50 winterberries per alt. Literally i can get a breather in 1 day or better say in a couple of hours…
Ofc i just dont care for the bubble skin at all

Key drop confirmed from treasure krait. Its some really bullshit low chance tho. Been afk farming with engi for about 3 hours to get one.

Just dropped a key from an Earth Elemental in Malchor’s Leap. Looks like Keys can drop from any mob.

his probably good for F2Ps . Me on the other hand have skimmer and bitterfrost, why do I care of this really?

There are up to +30 infusions and it’s the standard 2*N=N+1. That means a +30 needs 1,048,576 +10 infusions. Assuming there’s no way to get higher than +10 infusions, you’d need 957 years assuming 3 +10 infusions per day. Alternatively at the current price of 1.69g per +10 (with high prices at higher volume) you’d need a minimum of 1.77 million gold to make one +30 infusion.

I was farming and boredom found me doing a quest in Mount Maelstrom where an Ornate Rusted Key dropped. Is the reason I’m here as I did a search to see what it was.

Yowsa. O.o Guess I’ll be doing some cost benefit analysis over the coming days. My guess is I’ll probably go with a +15 when all is said and done. (After all, I’m still fully expecting an underwater mount to come out at some point if/when we get around to dealing with Bubbles.)

Dunno what Anet is thinking. Kinda pointless to make it this expensive, as no one will ever buy it.

anet will be dropping UW mounts down the road, this is just a grind fest to keep people busy till then, imo.

“There are reports of random key drops off killing mobs (i.e.kraits) but that hasn’t been verified yet.”
I got a key from sand Eel in Elon Riverlands.

“There are reports of random key drops off killing mobs (i.e.kraits) but that hasn’t been verified yet.”
I left my necro to afk farm and I got a key as well.

Something must be wrong in it, but the math for getting the breather or +30 is looking seems to be the following:
1 key a day
2-4 Infusions per chest/key = average 3
Therefore 3 Inf a day
256 Infusions for the breather = 85.3 days
Taking the infusion from +10 to +30 is as usual, therefore:
1 +30 Inf = 2^20 +10 Infusions = 1,048,576 infusions = 349,525.3 days?
Which is looking pretty ridiculous?

Hi Dulfy! You can also get keys dropped by killing krait mobs in fractals – number 38 dropped two for our party today and one from aquatic ruins yesterday.

Well, Maybe in the new maps we will be able to gather a new currency that can be exchanged for infusions.

Will bubbles strike tyria (or Elona) with a tsunami? Where?

I seems that you need to have a level 80 character to get a key by killing kraits. Or do I do something wrong.

The past two days I’ve gotten my daily key on a level 20-30 character, near Stormwreck Deeps in Caledon forest. Chat code is: [&BG0AAAA=]. I’ve noticed that risen krait don’t count, so that’s something to keep in mind.

thanks for this, I killed mobs in Caledon Forest, but still no key after 10, I will keep trying

Does anyone know if there’s a noticeable difference in swim speed between a +10 infusion and, say, a +13 infusion?

So the infusion count is 2-4 .. and it doesn’t spawn a Vet every time you open the chest.. They naturally spawn up to 3 Vets per location.

100% sure that keys drop from random enemies. i just looted one on my Istan farm character, and afaik there are no kraits there.

I have my daily done. Killed river drake lvl 7 in queensdale while visiting tp a got second key.

In our WvW-guild they drop frequently distributed over different players.

even as rnd-drop you need 512inf / (3inf/chest / 1 key/chest)=171 keys
just for the breather and for +30 infusion (2^20+10)inf / (3inf/chest / 1
key/chest) = 350,000 keys. I think, this might need some adaption from
arenanet… even with 1000 key drops per day, this would require you to
do that for a full year…

for a +30 infusion you need 1,048,576 keys and around 25K gold for the upgrade fee total (without price for the +10 infusions off of the TP)
assuming a average drop of 3 per key, and you get around 1 key per day, it would take 950 years to finish getting a +30

Yeah, when I saw that I would need 512inf for the ugly breather, I assume to pretend that this doesn’t exist and moved on.

You got 4 from the Sunken Chest. The 5 you see at the top is from when you right-clicked the reward chest for completing the achievement that’s still on screen. If you check the achievement panel you’ll see it awards 5 infusions upon completion.

Thank you for correcting me, I didn’t even notice that was the last one for getting the achievement even though it’s right there (I didn’t pay attention to it) I tabbed out as soon as I saw the +5. I’ll take it down so it won’t confuse others. Thanks again

Completed the achievement. After that I’ve tried to open chests for four consecutive days and it just says – You are unable to open the chest. I’ve done my 10 kraits for “blood in the water”, have key in inventory. Bug? anyone else?

Veteran Bristleback near the west side of Tarir (near spot of treasure mushroom and spring), drop The Ornate keys. I can send you screenshot if you want. Probably a rare and lucky drop, but your guide says ‘unconfirmed’ info.

already done with the achievement and is about 6/10 of the next but all the remaining 4/10 chest is now uninteractable. anyone having the same problem?

Yes. Same spot too; achievement completed, 6/10 & remaining 4 can’t be interacted with. I even checked the other 6 to confirm all 10 can’t be interacted with.

this is reported bugged maybe for 3 or 4 days already, i have it buged at FR DE servers for 3 days, at ENG server for 2 days

Nope. Still bugged and the key doesn’t seem to stack either. My unused key disappeared as soon as I receive another key from the daily quest. That’s two bugs in my case.

Currently bugged, chests wont reset therefore you wont be able to open them after you opened them once.

Till bugged… I could do the AP only once and now all chests are bugged. I want the AP and infusions, please Anet fix!!

I was able to do it twice, and the collection of the keys still works, but the chests are bugged. Means all open. Collection of infusions is not possible atm. Yes, ANET, pls fix.

I got an Ornate Key from a random drop from a Risen Eagle in Malchor’s Leap today… So I’d say random drops do happen.

“There are reports of random key drops off killing mobs (i.e.kraits) but that hasn’t been verified yet.”
It did for me!

Lucky day! Third drop today, from Harathi Hinterlands Bridge farm (lvl ≈40 centaur)
