FETH Save Editor

Note

Based on fe3h-editor by imouto1994, with v1.2.0 save support and game data from Falo.

Edit Fire Emblem: Three Houses saves, including inherited New Game+ progress.

Features

• Main: Edit player details, money, renown, professor experience and rank, activity points, goddess statues, game values, and monthly statistics. The inherited professor rank is available here too.
• Items: Edit inventory items and durability, restore durability to each item's normal maximum, sort the inventory, add essential items, and change miscellaneous item and gift quantities.
• Roster: Edit character stats, equipped abilities and combat arts, held items, skill experience, learned magic, flags, class experience and mastery, unlocked abilities and combat arts, and import or export individual characters.
• Battalions: Change battalion type, assigned character, experience, stored and equipped endurance independently, and skill; max the level of one or all battalions, replenish normal endurance, delete a selected battalion, sort the list, or fill missing battalions from the curated collection. Deleting an equipped battalion also unequips it. Equipped battalions can also be replenished from the Roster panel.
• Quests: Search quests and change their state.
• Support: Edit the current run's support ranks and underlying points, or raise every pair to its available maximum.
• Database: Look up characters, classes, and items without changing the save.
• NG+ Roster: Edit inherited skill ranks and class mastery for each character, or unlock every playable character in bulk.
• NG+ Support: Edit inherited support ranks and points separately from the current run, or raise every pair to its available maximum.
• System: Edit save-slot and unlock flags in the system save found alongside the selected slot.

Switch languages from the top menu. The interface and game-data names use the selected language where translations are available.
