I can't trigger Wendy's event to get her to join.
Never mind, I was able to trigger it after completing Ailluin's (the other archer squad leader) event.
I only know fire magic right now so that is why I noticed. You said that the slimes are only weak to ice magic, but they appear to take significant damage from the magic wisp spell from the copper scepter(you may want to increase its wp cost for doing three hits, as well as making scepters two handed and weaker one handed wands because right now I'm dual wielding two for increased magic damage), so are they weak to pure magic damage as well? The only other spells I could use on them were fire which were weaker in the rain anyway, so I never compared it to any other magic.
You said that the changes in scripts very rarely translate to old saves, but that would mean that they sometimes do. Would it be possible in a future release for the crafting list to be updated without having to start a new game each time. either regularly or with an item that updates the crafting list? I already have 28 hours on the game and don't feel like restarting and having to get my stats back up.
