A number of changes have been made to the base (vanilla) game to accommodate the open world randomizer. The vanilla game had no intent for visiting areas in abstract order, and certainly did not intend for visiting different worlds. First review the key items page to make sure you understand each key item and what it unlocks. This page will not always explain exactly why a change is made, but in general, the changes are made to accommodate either logical chains for player progression, or to prevent bugs. In particular, erratic game behavior arises when players transition between worlds when not using the WarpShard.

World 1

• The entrance to Torna Canal can be entered and re-entered to transport the player to the Ship Graveyard. The Ship Graveyard is a one-way exit to the world map, and the back entrance to the Ship Graveyard can not be entered from the world map.
• Access to the Catapult (Cid/Mid's secret underwater base) is granted via the Ruined City, which can be reentered until defeating Crayclaw. Upon defeating CrayClaw, Ruined City access changes to the Lonka Meteor, and access to the Catapult is granted via Crescent Town. Earth Crystal no longer influences world map change. This was done to clean up the world map graphical weirdness with the Ruined City meteor & town. The player will never be locked out of the Catapult area (access to Steamship) because Crayclaw also unlocks the base entrance

World 2

• The Cave of Jacohl exit into Bal Castle (Odin location) is now only a one-way exit. Meaning, the player can no longer go down the cave from Bal Castle. The door to Odin is always unlocked, from both World 2 and 3. The player can still access the Odin basement from Cave of Jachol in World 3 at any time
