Fishing treasure

Fishing treasure is the most valuable category of fishing loot. It can only be caught when the bobber is in open water. Its weight is 5 with quality +1. The chance per catch in open water is 5% with no luck and 8% with Luck of the Sea III, in any biome (see Fishing#Choosing the catch).

Loot

Several entries have a quality, so Luck of the Sea shifts the odds toward chests and Crystal Hearts.

Item	Count	Weight	Quality	No luck	Luck of the Sea I	II	III
Obol	1–2	72	0	42.11%	41.38%	40.68%	40%
Enchanted  Fishing Rod	1	42	0	24.56%	24.14%	23.73%	23.33%
Hell-Bound Book	1	30	0	17.54%	17.24%	16.95%	16.67%
Angler Pottery Sherd	1	15	−1	8.77%	8.05%	7.34%	6.67%
Goat Horn	1	5	−1	2.92%	2.3%	1.69%	1.11%
Crystal Heart	1	6	+2	3.51%	4.6%	5.65%	6.67%
Chest of buried treasure	1	1	+3	0.58%	2.3%	3.95%	5.56%

• The fishing rod is enchanted as if at level 30 and has only 0–25% of its durability left.
• The book is enchanted at level 30, giving a Hell-Bound Book.
• The goat horn can be any of the regular goat horn sounds.
• The chest is a chest item that holds a buried treasure loot table. When placed, it contains 2–4 raw diamonds (more with luck), 2 rolls of the treasure ores table, each giving 12–20 raw copper, 3–6 raw gold, 8–15 lapis lazuli, 8–15 raw iron and 1–3 raw diamonds, a 1 in 6 chance of 2 coast armor trim templates, a chance of copper, iron, gold or diamond nautilus armor, and a 2 in 3 chance of a sacred text (Paradise Lost or The Divine Comedy).

The developer made treasure rarer in 1.10 so that players who don't enjoy fishing don't feel pushed into it for loot.

History

0.5-alpha	Added Crystal Hearts.
1.10	Chests and Crystal Hearts made rarer, enchanted fishing rods more common. Buried treasure nerfed.
1.12	Buried treasure buffed slightly.
1.12.1-alpha	Treasure tweaked. Sacred texts made rarer in the buried treasure. The release notes also say nautilus shells were added to it, but the current fishing chest has none.
1.12.7-beta	Treasure went from 5% to 31.25% of open-water catches in biomes with fish, because the reworked biome entry has a weight of 1.
1.12.8-beta October 23, 2026	Back to 5% of open-water catches, as the biome tables weigh 85 again.
1.12.9 October 31, 2026	Treasure's quality lowered from +2 to +1, so Luck of the Sea III raises it to 8% of open-water catches instead of 11.34%. Every treasure weight tripled except the goat horn's and the chest's, which makes those two rarer: a goat horn went from 8.2% to 2.92% of treasure and a chest from 1.64% to 0.58%.
