Star Treasure Thieves’ Den Co-op Farming

Star Treasure Thieves' Dena.k.a STTD, Star Den, Thieves’ Den, etc.

With 9.2 fast approaching, so is the highly anticipated update to Thieves’ Den that nets 10 +eggs per run. Combined with co-op play, that’s 2.5 stamina/+egg, resulting in both the fastest and most stamina efficient +egg farming in the game (using the data from this site, not including stamina refreshes from rank ups). I think my best solo hour in the old version was about 400 +eggs, meaning I got 80 runs in. Co-op will be slower due to all the overhead, but even if you get, let’s say, 60 runs in, that’s still an amazing 600 +eggs/hour. It’s definitely worth making a team for this.

When you consider rank up stamina refreshes, other options have a better effective stamina/+egg, but none of them will be as time efficient. Even if you’re trying to be as efficient as possible with your stamina and stones, I’d still argue that this dungeon is worth looking into since it’s so time efficient.

Considering that the dungeon was solo farmable in the past, there really isn’t any new technology that would allow faster clears. The solo team can button floors 1-4, but generally relies upon a match of some kind to clear floor 5, usually a Goemon/Surtr swipe. Ideally you’d kill with actives rather than matching as it’s generally faster. Co-op gives you four extra actives to do just that, but it doesn’t decrease clear time as much as one might like (assuming it reduces time at all) due to having to pass the turn (and relying on your partner to be attentive).

However, our Lord and Savior MZeus once again shows us the path to a better clear:

Yes, you still have to match, but clearing a single column has much lower chance of unwanted skyfalls than a full board clear meaning clears will be faster over time. Rei Sirius is the preferred column spawner for inheritance on MZeus. He’s better than something like Cloud or Leonis since he doesn’t have a secondary effect that adds time to the animation. Due to this inheritance, there’s a fairly high skill boost requirement. A max skilled MZeus + Rei Sirius is at a 26-turn cooldown. Assuming an MZeus and four Tengus from your partner, that’s 18 skills boosts, meaning your own team needs to supply eight (or more specifically, your subs need to supply six total since MZeus has two). Even if your team is full ROdins, you’ll have 32 skill boosts total, meaning you’ll still need at least nine skill ups on your MZeus (or 13 total between your MZeus and Rei Sirius).

I also think most of these videos do the column spawn on floor 1; I’m not exactly sure if there’s a reason behind this besides pushing buttons in order, but it’s what I would recommend doing anyways. That way you have plenty of time to look at the board and plan your move; you’ll want to break up any horizontal orb pairs next to the empty column to reduce skyfall combo chances.

Need a poverty team? Well, our Lord and Savior’s alter ego Dios has the answer:

Pretty much as fast as the original solo ROdin-based team, but completely non-IAP.

Stuck in the area between poverty and luxury? There are still plenty of options:

You can look up for general farming teams on YouTube here and for MZeus teams specifically, here.

Anyways, if you’re serious about farming +eggs quick and efficiently, I’d highly encourage putting some sort of team together, then finding a like-minded player in a different group to trade urgent times with, netting you two hours of this wonderful dungeon. Of course, some people (that have the time) can get hooked up with five total hours which is pretty insane.

  1. King Arthur. From the GungHo collab PEM. Quite a rare pull,also that PEM doesn’t come aroudnpretty often. He does a 100x atk nuke to all enemies,reduces HP to 1 and enhances Balanced monsters by 2.5x for a turn. 14 turns base CD,down to 9 once max skilled. I only got one,back in December 2014,and kept him ever since. He also has 1 SB,so he’s really a worthy farmable monster.


  2. Setsu,i think it’s worth adding this video to the post :

    The main feature here is that you don’t need Arthur for this build. Compared to the Dios team it requires one more click,but it shouldn’t be a huge assle. I made the math,2 max leveled Goemons and Betelgeuse kill the blue demon without skyfalls. Devil Fishes must bet at level 19 minimum to deal enough damage to the green ogres. Betelgeuse at 15CD to alleviate the SB stress on the partner team as much as possible. One Goemon max skilled.


    • This post was not meant to be all-inclusive, just to give people ideas on where to start. In particular, to let people know that MZeus-based teams are among the fastest. Thank you for your input, though, as that should be an valuable option for many players.


      • Yeah,sadly I sold my only Rei Sirius more than 8 months ago and I don’t have any Rodin…. If I’ll ever roll a new Rei,I’ll put him on my MZeus (sigh Shinypiis) and find a coop partner without a skilled MZeus,as that team looks the fastest yet.


  3. Do you have a mech zeus and Sirius to inherit. I have both teams except for Sirius, looking for people to do some farming sessions once this goes live. I can share the load with either team if you are interested. 334,870,396


    • I do, but I already have a partner lined up to trade hours with. So unless you’re need someone to fill in for your hour, I can’t really help you. Also, my work will prevent me from being available outside the first 2 hours for most days. You can try pinging me on Discord if you need someone to fill in (setsugetsuka#3699).
