Let's start with the second one. While stepping on the enemy, jump behind him and press the left key to attack in the air. Remember that it's a blow, of course, it can be a combo, but it can knock the enemy to the ground. Press the E key after an attack in the air, and you will see the prince directly use the time dagger to collect the enemy, that's all. It should be noted that not every enemy adopts this tactic, and some can completely stop it. At this time, you can use it to attack twice in the air, you can knock down the enemy, and then use the E key.

The first one, jumping against the wall, has two uses. If you approach the city wall actively, it seems that it is not easy to push the wall and sprint, but it is easy to jump behind the enemy like the second one. If you want to make a wall sprint, it is usually at the time of the second attack, that is, when the enemy jumps behind him, it happens to be a wall. This is a wall sprint by pressing the jump key and the left mouse button at the same time.

And this killer skill you mentioned last time, yes, it does exist, but its power is not as great as you think, and it is more effective for the most junior soldiers. In the early mid-term, there were many rough-skinned guys, and this move could only knock them down. It may take two or three blows to get to them, which is not cost-effective. Therefore, this trick can only be used when surrounded by enemies, and it is more effective in places with many enemies and small activity space.

That's my own experience, brother. I hope I can help you.
