Here's my save for Fire Emblem Warriors: Three Hopes. To my knowledge this is as complete as you'll find it here or on any other site.
- Levels are maxed out for all characters
- All classes are maxed out for all characters
- Fully upgraded all unique weapons, such as the Heroes' Relics, sacred weapons, etc. Also includes a smathering of fully upgraded weapons of each types' highest tiers
- All characters have learned each teachable combat art and spell
- Note that I haven't bothered maxing out each combat art/spell level for every character as teaching them every art seriously burned me out, even while using cheats to let me use combat arts without cooldowns or durability loss
- Finished all routes, unlocked all paralogues, (renown) characters and endings
- Completed all achievments
Every stage I have completed is completed with an S rank. I completed every stage on all difficulties except Maddening. By that time I had sunk so much time into this that I settled for just getting the 50 wins needed to finish the last achievment and I retired from this game.
Some things that I didn't bother with is giving all characters every possible gift (shows up in a list which ones they like or dislike), nor did I bother encountering every question/topic on excursions. There are still many Merc Whistle gifts to obtain, but you can only get one per playthrough, so yeah...
Anyway, figured since I spent so much time on this game I might as well share the save file.
