This split has the most room for improvement in my opinion. I lost all 5 seconds I could of have saved from Lake Skip. You can do a lot more spam dashes than I currently do. The text box right before the first boss can either be walked straight through to the other side or possibly even dashed through. And the most important is boss rng. He can do shield bash repeatedly. If you dash and stop in him correctly you can just stand and just spam attack. 9 hits in a row is the best I've ever got. But the rng can be even better than that. So with all of this in mind. If the split was godly, we could see 10+ seconds saved here. Making potentially sub 5 a reality.
