TerrariaArchipelago randomizer mod

Defeating a boss still gives its loot, but the permanent world changes it normally unlocks may now arrive from someone else's game.

How the game changes

Boss defeats and event completions send checks; received progression flags control changes such as Hardmode and post-boss access.
Optional achievement checks and item rewards extend the item pool beyond world flags.
Play an individual world or a shared multiplayer world, linked to other Terraria worlds or entirely different games.
In-game commands expose Archipelago chat and the progression flags you have actually received.

The public Workshop item is available and not banned according to Steam's API, checked October 10, 2026. Its changelog documents mod 2.2 for stable tModLoader v2026.5. The page's hidden removal/incompatibility notification templates do not establish either status; availability also does not prove runtime compatibility.
The latest public client source is the repository's main branch, whose build.txt still declares 2.1; no public GitHub 2.2 tag or release was available when reviewed, so the Workshop 2.2 bytes cannot be matched to that source revision.
This is Seldom's implementation. Other Terraria Archipelago mods use different worlds and are not interchangeable.
Boss loot is not the same as a received progression flag. A defeated boss does not necessarily grant its usual world unlock.
The core guide recommends a lower difficulty than your normal Terraria run. Large progression-overhaul mods require their own compatibility review.
This entry conservatively lists Windows. Do not infer tested Linux or macOS mod support from Terraria's Steam platform list.
