Sooooooooooooooooo this is kinda pain. If you don't know 1.20 IH is done by unequipping the bow and then jumpslashing 1 frame later (1 frame after the pause ends) So yea it's frame perfect now I am getting a 30% success rate now so it can be timed but it's still really hard
DTG is already known to be doable on the ground by priming tulin and then jumping start holding down a and 1/2 frames after you start holding A hit ZL. This method cannot be done in the air, But DTG can be done in midair (if you want to find them go to the discord glitch hunting section and search, If this helps, tulin twice, I can gust again.) The reason DTG happens is Tulin enters his teleport animation on the same frame/1framebefore/1frameafter, He uses gust!
What really annoys me is that it cannot be replicated midair at all and cannot be replicated with deactivation, But the twist is deactivation does work with Sidon (And the ground DTG also works with sidon)
Get to a dog and unequip a weapon and do the animation of link not having a sword/bow equipped
