Build support through weekly meals and chapter restarts, and level through either dungeons or encounters. Money, dungeon sustain, and outfit changes each have their own steps too.
1. Restart after meals to retain Support
Find the character you want to recruit and give them a gift. Once contact is established, you can invite them to eat. The first gift need not be rare. An ordinary gift also unlocks interaction.
- 1Invite the target to meals at the inn and use all three weekly opportunities.
- 2Select auto-earn and arrange exploration, advancing to Sunday at 6 a.m.
- 3After meal uses reset, use all three again, then advance another week.
When too few turns remain to reach the next Sunday, open the system menu and restart the chapter. That chapter’s experience and other progress reset, but support and explored maps remain, letting you repeat the meal loop.
Choose a chapter with plenty of turns so you can fit more weeks of meals into each restart and reduce repetition.
2. Use an experience bonus in higher-level dungeons
First claim rewards from 
Eshmel. Spend 500 Karma Shards on the Boon of Salvation that increases earned experience by 10%. Then open the full continent map, filter for dungeons, and compare recommended levels to find one above your team. My example takes level-10 units into a level-20 dungeon, which levels them faster than repeatedly fighting weak enemies.
For distant dungeons, check for a nearby temple you can teleport to. Travel through its Divine Gate, then find an exit to the wilderness to save considerable travel. Temples marked with a cross do not allow direct teleportation, so do not head there simply because they look close.
3. Distribute experience in encounters
Red enemy tiles on the world map also provide leveling opportunities. The unit landing the final blow gains more experience, and healing grants experience too. Give kills to whoever you most want to train. Skip dungeon battle sequences with the plus button, use auto-battle in encounters, and disable combat animations to reduce waiting.
4. Earn money from golden enemies and exploration
Leda can perform in different places for Renown and money. If a golden mummy appears in an encounter, switch to manual control and pursue it. Do not let auto-battle allow it to escape. If it has plenty of HP, send several units after it. Defeat it for 
Bullion, then sell that at a shop.
Bring a 
Rogue on wilderness exploration to make perfect results more likely. Leda already suits a transition from 
Hunter to Rogue, so this fits naturally.
If you have nowhere to go, return to the inn for Auto-earn. With a small party, I earned over four hundred in one day of four turns. More members and more invested turns increase income. Use spare time before the main quest for this.
5. Reenter dungeons to restore Linked Attack points
If Linked Attack points run low in a dungeon, press plus to open movement assistance, return to the world map, and enter the same dungeon again. Your Linked Attack points recover, letting you continue exploring.
6. Wear original outfits after changing class
If you dislike a promoted class’s clothing, press plus on the Change Class screen to restore the character’s original outfit. This changes the initial clothing only. You can continue using the current class afterward.
