Introduction
With the anticipated release of the revamped Star Vault, Star Treasure Thieves’ Den (Star Den), we now have another means to acquire the coveted plus eggs. For 50 stamina, you are able to acquire a a guaranteed 10 plus eggs with minimal difficulty. This makes Star Den the most efficient place to farm plus eggs from both a time and stamina efficacy point of view.

Such buttons, much skill, very Plus Eggs
Damage Hurdles
The first four floors can have a maximum of 117,133 HP and is able to be swept with minimal combos or even a push button team. Do note that Goemon’s active 
cannot one shot a blue ogre so avoid using his active on those floors or bring a back up damage dealer such as Bone Fish, Fire/Wood, or Water/Wood Ogres. Furthermore, Red Odin 
requires 2343 ATK to safely nuke the Green Ogres down. This requires either:
- +40 ATK pluses
- 5 ATK
& 19 ATK pluses
The final boss floor has up to 1.9 million HP. The main benefit of running Star Den over Goemon, Zeus, or Valkyrie descended is receiving 1 extra plus per run and has the potential to be push-button farmed. Even if you do not have a team that can button farm Star Den, you can easily sweep the floors with a Two-Prong 
match and remaining actives for the final boss.
Plus Egg Comparison
Do note that all these values are for single player mode. Simply, double the rates for Stamina/+ and Exp/Stamina.

Conclusion
Even though some players may quickly mow through the dungeon, they still receive the same pluses per completion. They simply wish to acquire as many possible within their hourly limit and will repeatedly stone to do so. With the advent of stamina overflow, refilling stamina is a viable method and you can calculate your plus eggs per magic stone used. For example, if you have 150 stamina, you can expect 60 pluses per stone (in coop). This translates into 300 (60*5) pluses per REM roll. Just keep this in mind when deciding if it is worthwhile to stone for stamina.
Best of luck in your plus egg journeys.
Happy Puzzling!

Thank you for your kind words and encouragement! I updated my 10x chart to include the newly changed Tengu as he is now a viable place to farm plus eggs. =)

You’re aways very organized in your posts. the layout and all useful information.
About the dungeon, I cleared with my usual team without any trouble, the only modification I did was adding a menace for the final floor, so I had plenty of time for set up 2 rows to Raph do his thing.
God job and thank you again.

Thank you for the kind words =) I always trying to improve my formatting and hopefully what I am currently working on leaves an impression!
I do agree that the dungeon itself is not challenging, it is more so tedious and the real challenge is how fast you can go

Hi
i enjoy your posts, very informative. Where does the 20x +egg technicals fit into these stats? My own assumption is around 2 per run (7floors/13sta). Have you done any calcs?

The problem with 20x technicals is the variance of drops and can only be done in the 99 stamina levels. Thus your +/stamina is horrible. Furthermore, many can be pendras which makes it challenging to make an accurate calculation along with having to play on Mondays to ensure a guaranteed drop per floor. I would avoid technicals unless you are playing for the first time clear stone or need what ever drops from there.
3x normals with Starlight Sanctuary or Ocean of Heaven are much more efficient for pluses compared to technicals (may sometimes be on par with 10x descends but takes much longer to clear/farm)
Hope this helps =)

I usually run Mechdragon’s Massive Fortress (dark or light): no predra & ten battles for 50 stamina, usually I get between 3-8 + eggs. It takes longer than a descend, but is very easy to do 🙂

Actually, Mechdragon can be very very fast (read my article here: https://mantasticpad.com/2016/06/28/100-farmable-push-button-mechdragon-team/ ) as it takes only ~73 seconds to clear with a 100% farmable team!

Same system can be done with Zues Dios leaders, devil fish subs with one geomon sub.

Yeah there are def numerous different teams and I haven’t gone through the effort of Bone Fishing along with not requiring the ultimate team due to not stoning for stamina. Thus, I can take a few more seconds to complete and it’s not too much of a loss for me.
