its actually easier than i initially thought because this was only my 2nd attempt ,i also wasted quite a lot of time at amulvaro tower but i think its doable for everyone
and as you can see ,my attempt is longer than 4 hours but for some reason i still got the achievement ,i think that after you start the fight with endless ,the timer for the achievement stop and see if you can defeat her or not, if not then its gonna continue

also ,im an achievement hunter and this is the last achievement i have left in this game so imma jump to the next game .If you want to see me achievement hunting live then here's my twitch
