Duel him

You charge at him and swing your lightsaber in all directions to find an opening on him, but he deflects all your attacks. He is faster than he looks! At one point you try to use the force to push him on his back, but he ignites his jetpack and avoids the fall.

Pre (from the air): Your Jedi tricks won't be enough this time!

Lana: We shall see! Why don't you come down here and say it from here?

Pre: I won't give you the pleasure of getting defeated by the dark sabre kid!

He starts firing at you with his blasters, putting you on the defensive now. You deflect them back to him but he dodges them all and keeps shooting. One of the deflected shots now hit his shoulder! But it bounces off of his beskar.

Lana (letting your guard down): Wait... If these shots can't get through the armour why should I bother defending myself?

Your armour defends you from all his shots as none of them can get through the beskar.

Pre: Did you really think those were meant to defeat you?

He shoots a cable from his armband, catching you off guard and binding you.

Lana: Blast it!

You try to reach your fallen lightsaber but he gets to it first.

Pre: Ah, another Jedi defeated by the Mandalorians! Your arrogance to use the force makes you all weak! None of you could last long in a battle against us!

Lana: Release me and you will see what a Jedi is capable of!

Pre: I have already seen it... And you lost. You don't deserve your mother's equipment. You are a shame to all Mandalorians!

Rantar: Lana...

Lana: Father... I am sorry! I thought...!

Rantar: It is alright Lana! But I warned you not to do this!

Pre: But she did and now she has to pay for her arrogance to duel the strongest Mandalorian!

Rantar: Pre, don't do THAT again!

Lana: "That"?! What is "that"?!

Pre: You will find out soon enough!
