Even at my level

I've pretty much never used assists. The characters I raised myself and bought weapons for are stronger anyway...

I haven't really used assists much either. When there are limited-time characters, I feel like using them, but I always end up sticking to my own reliable team setup.

I use the skip function anyway, so I don't use it unless it's really necessary for a mission.

I skip events unless I have to include a specific character in my team, and choose other paths. I'm working hard to collect coins because I can buy summon tickets with cave coins!
