Warm Ocean Ruins Map is an explorer map that marks the location of a set of Warm Ocean Ruins. It cannot be obtained from the Creative inventory and is not among the trades offered by cartographer villagers.
In Java Edition, the Warm Ocean Ruins Map generates as loot inside the secret chest of an Abandoned Camp, where it is one of seven possible explorer maps that chest can hold, each with a 14.3% chance to appear.
Like other explorer maps, it does not render full terrain detail. Instead it shows only the land-water outline of the surrounding area, with an orange striated texture marking water and a blank texture for land, a player marker, and an icon pinpointing the ruins. When the map is generated, it searches for ruins around the chest that produced it and skips any structure an earlier map already marked, so the one it shows is not always the closest.
Once the player reaches the mapped area, the Warm Ocean Ruins Map fills in like a normal map. The player's own icon shrinks when they are a great distance from the mapped area and returns to full size once they are close to the map's border.
The structure a map leads to depends on the trading villager's biome. Each of the two or three possible maps is a separate trade, so one villager can offer several maps.
