All achievements gotten. 3 hours for Cancer Speed, the rest of the time was spent grinding attempts in order to get powerful enough to... no-hit a specific boss.
Still missing wins with a few characters but that isn't an achievement.
All remaining MarisaA spells captured, some SakuyaA spells captured, enough to reach my score objective. Now whether I capture the rest it's up to my willingness.
First easy mode with no upgrades, then hard run clear, then hard run with 50k gold. Then finally the challenges. Did not have to grind because I could simply do challenge 4 again.
Replayed the game, went straight to grind Super Gauntlet on Judgement with no regard to practicing any stage, even the newer ones. Cleared it (with continues).
While grinding for Version B medals, got the 2-ALL with Sadahl, the one character I was missing his ending and better than Loop at certaing things. Then grinded a bit more and got the medals.
Beat the game with a continue, then again (both on hard) with 1.5M points. Then grinded the start of level 5 for the 10k kills, killing my character to force end the run because it doesn't save otherwise until the end of the level.
