You can farm up to three memory shards per character in Crossing World’s Memory Retrieval stages (at the last stage, you get 9 shards a day).
Some characters have star breakpoints that significantly improve their kit. Your farming slots will vary based on your roster (e.g. don’t farm Col if you have Rawiyah - Nostalgia). Unless you pull for dupes, you’ll likely never have free slots to push characters past the recommended breakpoints.
