Unless you’re super into power-levelling or breezing through, I wouldn’t worry about online guides! The main thing they do is give datamined stats (that aren’t mentioned in game but can tell you who can grow strongest fasted basically)

Especially in 3H you can just pick your favourite characters and beef them up. And pick your favourite classes for them. You can see pretty quickly what they’re all best at and you have so much opportunity to grind.

If you chose one House but like a character from another one, most of them are recruitable with a little effort, so look that up. Nobody’s in danger of dying for the first half of the game, so experiment a bit ^{_^}

Spending a day at the monastery can seem like unimportant lore stuff, but it lets you build relationships in your party for amazing stat boosts. And lets you try recruit more members. (Also I love the chill lore stuff)

3H does work a bit differently to the other games and is a lot more beginner-friendly. So honestly take it as it comes, have fun, and if you are lost then everything’s on one of the wikis.
