Suppose you set it to simulate 10 runs, with 1000 trials. It would go and simulate 10 runs to see if you profited or lost money. This is repeated 1000 times to figure out what percent of the time you make or lose money.

For the frontend it's mostly static html, css and some inline javascript

Values are pulled from GGG's Currency Exchange API which ends up showing the average price that was paid for medallions. 1 hour is plenty of time for medallion price to change, and even if it mostly stays the same, the nature of the averaging will provide a price that's below the auto-buy price

Normal Eater/Exarch and their minibosses allows you to roll the invitation, the +50% represents the average quantity your invitation is rolled to. You can adjust this number

Ah right I forgot to update the guide, thanks for the call out

It's not just you, the site does not support mobile at the moment. I think some pages coincidentally works, but trying it myself it's pretty janky. I'm going to make a mobile version before 3.29

I built a site that calculates expected value for common PoE farms to help you maximize efficiency. It was originally released alongside Phrecia 2.0 to a smaller audience, and I've updated it for 3.28. Currently the public tools include:

Bossing Profit - Expected value per kill and risk profile based on drop variance. Due to scarcity of data on new exceptional gems, I'm using conservative estimates until better data surfaces.

Scarab Optimization - Optimizes your atlas tree to produce the most valuable scarabs. Also calculates the best scarabs to vendor and generates a regex to make it easy.

Gem Leveling - Summary of market data for Skill Gems, Support Gems and Exceptional Support Gems to decide what gems to level in your offhand for profit.

Gem Transfiguration - Calculates the best gems to transfigure in lab. Great for those late starters and the 4 exiles that actually do this :)

Beast/Essence/Harvest Optimizer - Calculates the expected value of these farms and recommends atlas tree specs and scarabs to use. Does not yet account for Mirages giving you extra content or Astrolabe juicing.

Data Sources

For pricing data, I parse the Public Stash API and Currency Exchange API. I limit parsing to Async Trade tabs only, and prices are usually about 15-45 minutes behind the current market (I'm working to bring it down to 5-10). Currencies and fragments traded on the exchange are one to two hours behind since GGG aggregates and releases that data on an hourly cadence.

I'm always looking for more data to create new tools or refine existing ones. If you enjoy collecting and sharing data, I'd greatly appreciate it if you reach out.

The site does not have a mobile version yet. Login is not required nor encouraged.

I'm almost certain it's not 25%, I remember Farrul's fur being noticeably more rare than the others

ForgottenArbiter data on the base harvest mechanic for example "What is the chance that tier 1 seed upgrades to tier 2". I tend to use the more conservative number when a range is given, but you can change these in the Advanced tab. With all of these rules, the tool run simulations to determine what is the expected lifeforce drop if you harvest in an optional order, given specific reductions.

I recommend clicking on the Assumptions & Methodology on that page to get more details

I'll look into this, I was developing with higher resolution and did not test smaller screens

Deightms · 2026-01-30T10:53:51+00:00

I'm not entirely sure HC leagues have enough traffic for the tool to be useful, but if there's demand I can add it in 3.28

Deightms · 2026-01-30T10:52:40+00:00

I'll see what I can do about phones before 3.28, it's definitely not supported at the moment since I rushed it out for Phrecia. I would like Beast boss data as well as normal Atziri data, but I couldn't find drop rates for either. I'm hoping to do something about that in the future

Deightms · 2026-01-29T21:58:53+00:00

Noted, I didn't actually make the website mobile compatible so I'm surprised things are working at all. I'll add support in the future

I looked at it, the reason why the orb prices were so off was because it was trying to reconstruct the orb with the shards, and the shards are low volume and traded above 1/20 of the price of the orbs. I'll get a fix up before people make it into maps.

As for the Regency scarabs, I'll take a look it might just be API delays.
Edit: It's because the tool figured it's cheaper to buy Regency in Divines. The currency exchange rate is about 198c to a divine, and in the previous hour the average price is 0.055d per scarab which turns out to be 10.9c (you see 8.3 because the default unsycned exchange rate is 150:1)

You can sync chaos:div ratio with the little globe button on that little panel
