KT (Karmic Transformer) glitch is a trick that exploits a glitch in the Karmic Transformers and allows Amaterasu to jump infinitely. Due to needing Karmic Transformers, this glitch is only possible in NG+. In the versions after the PS3 version the regular KT glitch in mid-air has been patched. This means you can only preform this glitch on the PS2, Wii and PS3.
The glitch is performed by using a Karmic Transformer while in the area. Immediately after switching KTs, close the menu and press the dash button on the first frame after the fan closes. This will allow Amaterasu to do a ground dash while in the air, and a ground dash can be interrupted by a jump input. Due to being frame perfect, this glitch can be extremely hard for new players so it is recommended to use the video tutorial to learn.
Note: A normal KT cannot be done over water, however a similar glitch called a liquid KT can be performed to infinitely jump over water.

A Liquid KT is a KT preformed over water or lava. It works slightly differently not requiring the frame perfect dash input.
It works by doing a regular air dash close above water, then quickly opening the menu to switch KT. After the menu closes, you have to time a jump input to get the jump. The quicker you are with opening the menu after the air dash, the more momentum you'll have after the KT. Also, if you jump on the exact frame the menu is closed, you'll lose the air dash you usually get after preforming the glitch.
Slope KTs work very similarly to liquid KTs. The main difference is that you don't even need to do an air dash to get it. Simply be touching a slope, the type where you slide off, and switch KT. You can jump in the same way as a liquid KT. To make life easier, dash into the slope and the moment you bonk preform the KT. This way you won't lose extra height to sliding on the slope.
