Ocellus Simulator OSR – Practice the Archive Ocellus Fight Online

Archive Ocellus Trainer is a free practice simulator by Julian Dasilva, with help from Alessandro Rodi, for the Ocellus encounter in The Fractured Archive. Players may also search for it as Ocellus Simulator OSR or Ocellus simulator.

The trainer lets you select a starting phase and weapon setup, enable learning markers, and practice with a safety option. It is useful for isolating movement and response decisions before trying the encounter in the game.

The project is in early development. Its developer says mechanics draw on community information and release-day reports, and timings remain unverified and may change. This fan project uses Jagex intellectual property under its fan content policy and is not endorsed by or affiliated with Jagex.

Fight Setup and Learning Aids

Choose a starting phase from Corners, The Blade, Quadrants or Phase 4, then pick a starting weapon setup. Turn on Practice before you begin if you want to prevent death and keep prayer active while learning.

Select Start fight when ready. Click a tile to move; hold Control while clicking to walk instead of run. Press P or Pause to pause the encounter. Danger tiles and destination markers can help you read the arena while you practice.

In Phase 4, the inner void covers the 5-by-5 area around the boss, while the outer void covers the remaining floor. Watch for marked explosions, use the appropriate defensive prayer during transitions and deal with void rifts.
