I declare victory
2026-Mar-20, Friday 17:40After a couple dozen more hours, I've beaten all the original post-game content for Clair Obscur:

This is the E33 ultimate superboss. I spent a while grinding while listening to podcasts and then fought him a few times. I could have fought him a lot more, learned the exact timing on his attacks, including all the double and triple attacks he does in later phases...but no. I abused a bunch of pictos to get extra actions, did damage stacking, stunned him at 40% health and then slammed him with a level 3 gradient attack to skip Phase 3 (that's the 16 million damage highest attack I did). That finished off my last achievement, making E33 the seventh game I've gotten all the achievements on.
Just need to do the new DLC area they added a couple months ago and then I can move on to something else.
