Now it's been a while and I forgot because I haven't played KH3 since I initially beat it [to include RE:Mind] but now I'm playing the entire series on Proud Mode and I'm not far from moving on to KH3. I know it's possible to get Ultima, Oblivion and Oathkeeper on a New Game+ but I forgot exactly how to go about it, can someone give me a refresher as to how to get all three keyblades on one save file? 

For Oathkeeper - find all lucky emblems.

For Oblivion - clear game on critical.
