A wrong warp can get you past this gate into Severed Tower at the beginning of the game but wrong warps put you into a state called limbo where you can't attack or interact with anything. But there is one thing you can do, you can open a warpgate, all you have to do is walk into it's room. You just need a way to save after walking in which a death would solve. This currently does not work as a viable trick for two reasons.
1. There's no current way to scale the room next to Sinodo in limbo, wall jumps don't work. I use debug to scale it in this video.
2. Dying is the only way to save your game here, and you can't get hit by anything in limbo. The only way to die is to clip out of bounds which I use debug for here as well.
If you can find a way up the wall jump room and you find a way to clip into a wall in limbo, then Sinodo Skip might just be possible.
