The Hess with a bombchu only works as Adult link because Child Link not only moves slighly slower, but also has a shorter attack range. I have another setup with bombs that are more accurate.
Whenever Link is in the ESS position, he siderolls when A is pressed. If Link siderolls right or left away from a bomb, he will not take damage and have a HESS set on a 90 degree angle. This is more accurate than using a bombchu, but it is slower.
And Ben, I really suck at HESSing off of enemies, so bombs aren't really that bad. :)
Thanks PedalPower, though I haven't created a route yet. There are still plenty of things I want to find, like more Boss Key skips.
Speaking of Boss Key skips, there's one for the Water Temple in MQ now. I found a new clip with the hookshot when you buffer it with a good angle upon a corner and stop, Link's hand will clip through two walls and be able to shoot it upward. With this new glitch I was able to shoot up at the hookshot thing on the right near the boss door (as some doors can be clipped as well) to clip oob and then I shielded a bombchu (there's no void so it doesn't crash) and the damage boost made me land in the boss door. This dungeon can be skipped completely now, but I don't know if I am able to just yet. Soon I'm going to have to check 2 hookshot places to see if I can skip the longshot.
