Hero Siege Bosses

Use this directory to identify a boss and its recorded location, then verify the route in the current game. The 16 entries below are grouped by their recorded act or activity. An act label is a navigation aid, not a recommendation that the encounter is suitable for your character.

Plan around a verified reward: This dataset does not establish boss-specific drop rates or complete loot tables. A historical Farm label does not prove that an encounter is the fastest way to obtain a particular item. Check a current loot source before spending keys or repeatedly running an encounter.

Compare runs consistently: Record the difficulty, time spent reaching the boss, fight time, deaths, and useful rewards. Change one setup element at a time. A faster fight can still be a worse farming route if reaching the encounter or recovering from failed attempts takes longer.
