Twilight Princess: Notable Events and Route Deviations

List of all notable game/overworld events that impact the progression of the game.

This is a list of (hopefully) every important event required to complete Twilight Princess normally that I'm dumping here. I've omitted a few events (such as the first King Bublin Fight) that don't appear to change the inventory or progress the game. Sometime in the near future I plan on making a list of odd deviant routes and subroutes to map out every possible sequence order.

Notes: Tests have only been done with BiT Save during EMS A subroute. Subroute ends in a dead end for now. If Kakariko Twilight is cleared before Opening Kakariko Gorge Portal, the event is permanently skipped. In theory, it may be possible to enter and beat Goron Mines early with BiT Save without EMS A. More testing is needed

Early Access to Master Sword Subroute
Start after event: Open South Faron Portal, though it's more practical to get the vessel of light first
Skip Events: None

Use Howling Stone to open Lost Woods
Solve Golem Puzzle

Early Master Sword Subroute A

Notes: Goron Mines can be entered later with the spinner. Early Master Sword causes several game events to 'break'

Early Master Sword Subroute B
Start after: Early Access to Master Sword Subroute
Skip Events: None (this subroute was created to obtain Bombs/Bow before Saving Midna)
Important: If the Goron Mines can be entered without wrestling Cor Goron that doesn't involve the spinner, this will be obsolete

Save warp, deathwarp to return to Normal Route, leave after Goron Sumo Wrestling
Obtain Oocco from Goron Mines (for easy access)
SB: Early Sacred Grove as a human
Obtain Master Sword
Return to Normal Route

Notes: On the Wii, Early Sacred Grove as a human is only possible with a bomb boost. This is the only Subroute that can temporarily escape from the Midna's Desperate Hour subquest.

Endless Midna's Desperate Hour Subroute
Start after: Early Master Sword Subroute B
Skip Events: None
Important: Do not obtain Oocco from Lakebed Temple, or else it will disappear after the temple is complete.

SB: Use Goron Mines Oocco to warp away from the Midna Barriers around Hyrule Castle

Notes: Midna cannot charge attack or warp. Also, Midna's Lament will play continuously in almost every situation. Entering Hyrule Field will force the time into a continuous night, and except for the enemies in North Hyrule, it's devoid of enemies. From here, your limited in what you can do. You can reach Gerudo Desert provided that you haven't warped the cannon before clearing Lakebed Temple. If you beat Arbiture's Grounds, you lose Oocco, which traps you in the Mirror Chamber.
