The odds

- Laboratory treasure pile (tier 10): 1.7% of eligible pieces roll Legendary; this record is from 1 in 1.4 to 1 in 1.6 of those, by base piece; about 1.1% to 1.2% per piece
- Dragon's den treasure pile (tier 18), a place of another family: 2.9% of eligible pieces roll Legendary; this record is from 1 in 7 to 1 in 8 of those, by base piece; about 0.37% to 0.42% per piece
Odds are per weapon, armour or jewellery piece in the loot, at Luck 50 with no finders. See Item rarity for how luck and the dry-spell bonus change them.

How it drops
Where it drops
There is no monster that carries Worm's Tooth and no chest that holds it. A weapon drops first (Dagger, Tanto), and if that piece rolls Legendary on the ladder, the game picks one named record that fits it. Records found among spell-casting sources weigh five to one, so Worm's Tooth is far likelier from the places listed here. Any weapon, armour or jewellery in any corpse or treasure pile can be rolled, so a source of another family can still give it, at the lower odds shown on the last line.
Getting the base piece
A piece has to drop before it can be Legendary. Weapons come from the weapon chance on a loot table (see Loot tables), and from the kit a foe carries: an Archer carries a bow, a Warrior a heavy weapon, and so on (see Enemy kits). The odds above are per eligible piece, at Luck 50, with no finders. Luck, Foxglove and a long dry spell multiply them, as the Item rarity page explains.
Items (legendary pieces made from it)
Dagger
TantoLoot rarity is on by default and forced on online. A Legendary is the second rung from the top of the ladder (Common, Magic, Rare, Legendary, Aetheric, Artifact, Gilded). Its bonuses are fixed; only its condition varies. Foes of its family drop it five times as readily as any other.
