Collection Log
Select an item to see each member’s exact contribution.
The percentage on an item is the pooled percentile for the currently selected members: their observed copies are compared with the probability distribution expected from their combined eligible boss KC, raid completions, clue completions or other relevant rolls. A 90th-percentile result means roughly 90% of equally exposed comparison outcomes would contain fewer copies; a 10th-percentile result means roughly 90% would contain more. Ties are handled at the midpoint of the discrete outcome.
Selecting one member therefore gives that player’s result; selecting several members combines their drops and eligible rolls into one group result. The item detail still shows each selected player separately. Percentiles are omitted where the saved data cannot supply a defensible denominator or where the mechanic is not modelled reliably.
Raid assumptions and historical limitations
Chambers of Xeric: almost all recorded KC predates the 12 August 2026 loot rework. Pre-rework completions therefore use the historical 69-weight unique table. Normal CoX assumes 30,000 personal points per completion, representative of a deathless, non-scaled solo; CM uses 62,000 points for a timed deathless solo. Exact historical points are unavailable. Big Dog Aura is an important exception: a large proportion, probably the majority, of his normal CoX KC was scaled. A sample of roughly 100 screenshots indicates his true average points were higher than 30,000, so the site likely overstates his CoX luck slightly. In other words, his real CoX RNG was probably a little worse than the estimate shown here.
Normal ToA: modelled as roughly raid level 150, deathless, without skull skipping, using a fixed ~1/45 purple chance (about 16,667 equivalent reward points in the standard points model).
Expert ToA: modelled as roughly raid level 350, deathless, with skull skipping, using a fixed ~1/16 purple chance (about 21,875 equivalent reward points). These are representative assumptions, not reconstructed per-raid histories.
