How Ghorm was identified
Ghorm is listed above under its real stats, and getting there took a detour worth stating. No entity in the files is named Ghorm, so this site previously said the encounter had no boss entity and guessed it was built from worm segments. That guess was wrong.
What settled it: every trophy is a boss-specific item, and across all 75 trophy objects that
appear in any loot table, each is dropped by exactly one table — and wherever the
boss is independently known, that table is its own. GhormTrophy appears in exactly one
table, and it belongs to BossLarva. The same rule independently confirmed the Hive
Mother's drop table, which had been an inference until now.
How to read a drop table — and why other sites' percentages are too low
Each boss table draws a fixed number of unique drops, weighted, without replacement. So an item's real chance is not its weight divided by the total: several draws happen, and each one is another shot at it.
The difference is not small. Azeos draws 6 unique items, so Scarlet Ore at weight 0.17 is 85.5% per kill, not the 21.5% that weight-over-total suggests — and the necklace is 29%, not 3.8%. Any site quoting the single-draw share is understating real drop rates roughly four-fold.
We publish the true figure. It is computed exactly rather than simulated: sampling without replacement is equivalent to an exponential race, which makes the probability a definite integral we can evaluate directly. The implementation is checked against brute-force enumeration of every possible draw sequence on every build, agreeing to about one part in a billion.
