You dont need that much, i will explain.
I have gone random with lvl 50 something a lot of perks and a lot ton of saves using the as pose and then repeat power up and strong thrust while you save before you use the move and load that save over and over again until you get a crit and in 3 to 4 hits you can win but you will be stack for hours if your unlucky.... like me, and im a sore loser 😑. Oh, and sorry for my bad english.😅
