The Loot Generator API creates random loot items by combining:

• 30 adjectives
• 29 materials
• 15 item types

resulting in 13,050 possible items.

Occasionally, a rare legendary item is generated. An item becomes legendary if all three components are rare. Rarity is determined by a threshold:

Threshold = max(1,⌊log(length)×0.6⌋)

Probability of a legendary item with the default settings:

P(Legendary) = 1/13,050 ≈ 0.00766%

Only one legendary item is possible: ✨💎 Arcane Diamond Rock.

You can expand the lists or adjust the 0.6 multiplier to control rarity.
