Welcome to Mirage league! All item prices are live data sourced from the Public Stash API (5 minutes behind live trades, per GGG) and Currency Exchange API (~1 hour behind the currency exchange, per GGG). However, many of our Expected Value calculators depend on community-driven drop weight data that takes time to update each league.

Here's where things stand:

• Scarabs — Weights are from 3.27 and likely incorrect. Scarabs have been added, removed, and renamed this league.
• Boss drops — Using 3.27 drop weights until new community data comes in.
• Beasts — Assumed unchanged, except most Harvest beasts which have had their weights increased by a modest 2x.
• Essences — No changes expected.
• Harvest — No changes expected to the mechanic.

Gem Leveling (New)

• Added tool to help users figure out what gems they should level for profit

Boss EV

• Added preliminary Exceptional Gem drop rates. For ones I don't have data for, I use a base 2% to be conservative. I will update as more data comes in.
• Made it clearer when item prices are derived from unidentified items i.e. Watcher's Eye, Bound by Destiny, etc.
• Catarina unique prices now uses Veiled unique price data instead of cheapest unique available (drastically increasing Catarina's EV calcs in the process)

Essence EV

• Fixed issue where Kirac mod was still available in the configs
• Fixed issue where Essence Scarabs was adding 1 less essence than it should be

Scarabs

• Added more data to Scarab tool. Sample size 5k -> 16k (Special thanks to contributors for the data).
• All scarabs now eligible for vendor regex (previously some scarabs were not listed on exchange and had no price data)

Bugs

• Fixed issue where first time users see default chaos:div ratios on first time visit
