The game's own map, every place at its in-game position. The list on the left has three tabs — places, uber bosses, chests & other sources; click an entry or a marker on the map to see its drops and odds. Search an item to light up everywhere it drops, and hover an item in a drop list for its stats.
Blue = zone · red = boss dungeon (the act boss stands on it) · gold cross = the act's dungeons · badge = town. Drag to pan, wheel to zoom; the act buttons jump straight there.
Map, markers, boss and item art are the game's own files, copyright Panic Art Studios. Marker positions and routes follow Parazeya's hs-map; drop odds come from the HS Tracker datamine. Unofficial data, may change with patches.
