Its funny cause the mist covers the entire radius from short range to mid range, rendering your techniques completely utterly useless since you have no idea where I am and didnt even say you targeted my former location. Also pressure damage requires no handseals lol. Also Im assuming your using stone spikes since you said that...

As I see you creating spikes in random places due to my Byakuugan I see where they are and know not to go near them to be impaled. So as your creating your spikes I slam my hands on the ground opening a small hole a little behind you completely silently, I then exhale into the hole creating lava which comes up behind you torching your back, this technique happens as your slabs of earth come up. As your back is being burned I exhale a fire technique quickly followed by a wind technique straight at you, seeing as you cant move backwards due to the fact that lava is erupting behind you and a fire wind combo is coming at you from the front which you are still unaware of.
Note: The crater tech happens a second before you create the slabs of earth and is a foot behind you.
