We all have made beginner mistakes. Maybe it was ignoring Hans because of his introduction, or caster supports altogether. Maybe it was overlooking low rarity servants, or it could even be ignoring certain event CEs. However, which was your one mistake that trumps them all and affects your FGO experience to this day?
In my case, it was related to Kaleidoscope. I started the game not long after the launch of the NA server, and back then I never considered starting NP CEs particularly useful, as I wasn’t aware of battery options and 3T setups and all that jazz, and instead I was all about CEs that made damage numbers bigger, because bigger is better.
However, as if to spite me, I actually managed to pull three copies of Kaleidoscope in the first week of playing the game (hell, I can’t be sure, but I think one of them actually came from my first 10 pull), and in my ignorance I have proceeded to limit break one of them twice instead of holding onto them.
Since then, I never pulled a single Kaleidoscope, and thus I am feeling the effects of my stupidity to this day, as the lack of extra scopes makes a lot of great 3T farming strategies either really complicated (having to rely on time-consuming plugsuit-juggling) or straight up impossible.
