Gemcheck – Poe Transfigur

GemCheck overlays a floating panel on poe.ninja's skill gem price page and
instantly tells you which transfigured gems are worth hunting at the
Labyrinth Divine Font.

─── HOW THE DIVINE FONT WORKS ───────────────────────────────────────────

The Divine Font offers two ways to transfigure a gem:

Color Roll — insert any gem of a colour and receive a random transfigured
gem from that colour's entire pool (equal chance for each gem in the pool).

Specific Roll — insert a specific base gem and receive one of that gem's
transfigured variants at random (equal chance per variant).

GemCheck calculates the expected value (EV) and hit probabilities for both
modes so you can make informed decisions before you run the lab.

─── FEATURES ────────────────────────────────────────────────────────────

DIVINE FONT (Transfigured Gems)

• Color Roll Bingo — for each colour (Red / Green / Blue) shows the top
target gems with their hit probability and current sell price.

• Best Specific Gems — a combined cross-colour ranking of all base gems
sorted by EV, with every variant's probability and sell price listed.

• Gem level / quality filter — choose between lvl 1 q0%, lvl 1 q20%,
lvl 20 q0%, or lvl 20 q20% to match what you actually sell.

• Gemcutter's Prism price — shown in the status bar alongside ×20 cost
so you can quickly judge whether quality is worth it.

HARVEST SWAP (Orbs of Alteration)

• Catalysts — expected value for swapping Catalysts via the Harvest
crafting bench, ranked by EV with individual hit probabilities.

• Essences — same EV analysis for Essence swaps.

• Delirium Orbs — EV for Delirium Orb swaps using experimental
drop-weight data (credit: lifewithoutpants_ on YouTube).

GENERAL

• Live pricing — pulls directly from poe.ninja's API for the current
league. Data is cached for 5 minutes; a Refresh button busts the cache.

• League auto-detection — reads the league from the poe.ninja URL, so it
always shows data for the league you are browsing.

• Responsive panel — widens into a two-column grid layout at larger sizes;
draggable and resizable, minimise or close when not needed.

• Configurable Top N — choose how many items to show per section (3 / 5 / 8).

─── USAGE ───────────────────────────────────────────────────────────────

Navigate to poe.ninja › Economy › [your league] › Skill Gems (or Currency,
Essences, Delirium Orbs). The GemCheck panel appears automatically.

─── NOTES ───────────────────────────────────────────────────────────────

• Prices shown are raw sell prices (cheapest non-corrupted listing on
poe.ninja). Base gem cost, lab fees, and orb costs are not deducted.
• Harvest swap EVs use baked-in experimental drop weights; individual
results will vary.
• This extension only runs on poe.ninja. No data is collected, stored,
or sent anywhere.
• Gem pool data sourced from the Path of Exile wiki.
