Details about the speedrun that may not be obvious by watching the playthrough: Brub has the strongest single-target attack, stronger than any other creature, so it is primarily used, with Ormagon used for multi-target attacks. I don't used Leaf Essence to deal extra damage (+25%) as it has extra dialogue. I'm not sure if it is faster or not. I also don't use terminating attacks as most creatures die anyways in one hit, but it may be faster with good RNG.
Some scenes crash if an interaction occurs within 32 frames of the scene loading. I talk to Eidon from the south to get the Crystal Gloves to avoid this crash, and this is why the game crashed right before the credits.
By doing a perfectly down-right diagonal after using the Eldritch Awl after getting the Blurry Scroll, it is possible to, in the overworld, phase in-between the left and middle house and reach the right house.
I used the Warrada Skip bug: If you go to the inside of the Orothe House after Oscent Mar has left the area, Warrada's boss fight will be marked as completed and skipped.
I made 3 pathing mistakes: I had to redo the Orothe Geyser, and I had some small mistakes in the Arderial Geyser and the way back in the Arderial Clouds. In total this cost around 3 minutes of time.
