i'm thinking about through trials and galaxies again.
i think there would be a decent amount of breakcore
also, new idea for a memory: "Memory of Violence" which could be gotten by somehow triggering the tutorial event twice. this one would make it so that upon entering battle, siffrin uses "Just attack." on the most powerful enemy (most hp) in the battlefield. all battles ended with this attack will give siffrin 10% less xp, does not affect the party's xp gain.
how you would trigger the tutorial event twice: during act 4, with all the requirements to go into act 5, do not talk to loop and do not attempt the friendquests, causing siffrin to Just Attack again. he will immediately rewind to the field and berate himself for making the same mistake twice. (this would be added because i hate the encounters during act 5 due to being pointless and slow and using Memory of Sadnesses is kind of boring)
