Nice!
I recently went back to elden ring and replayed it. I had missed her on my first game so i did NG+ and wasn't leveling so i could still help people at the end of their first playthrough. I got so close on my 2nd attempt and then she murdered me like 30 times. Next day i beat her first go. Ive since successfully helped over a dozen people beat her, though many of them died to her waterfoul dance 😅
I haven't decided if i want to get the DLC or not. Might wait for a sale
Also, at the end as long as you don't begin NG+ you can still go through and do stuff and start NG+ later. You'll just be locked out of some stuff in leyndell since it's Ashen Capital now but that happens after maliketh so no difference for you now one way or the other.
