The Legend of Heroes: Trails in the Sky the 3rd

• The Shining Pom enemy seems to have been supplemented with enemies of a similar archetype. The Slime Lump enemies will yield around 100 sepith of the Mirage, Time, and Space elements, while the Aries Pot enemies will yield similar amounts of the other elements. Shining Poms are still in the game, and yield around 70 of all elements, but they're much rarer, harder to kill, and don't yield as much experience as in previous games.

• Don't underestimate Tita's utility, especially in the early game. Despite being worth about as much as a sack of rocks in FC/SC, her crafts and high damage will often carry your team.

• Activate doors as you find them even if you don't want to enter, just to get them on the map for later. It is still recommended to do doors as soon as possible, as the rewards for completion tend to be good, and you get mira for completing doors.

• The first door you encounter has two parts. You'll need to return to it later. This is the only time that happens, though.

• Some doors have story battles as part of them. Winning the battles can offer a better reward.

• Don't forget to take advantage of support characters. They offer a variety of different benefits, usually in exchange for a drawback. If a boss is giving you difficulty, consider adjusting what support character you are using.

• Two strong, mutually exclusive quartz are available from the fountain in the final chapter depending on your actions. If you have fought 300 battles and have never fled from a battle you get the better one. If you have fled 300 times before starting the final chapter you can get a different one. You can only get one of those on a playthrough.

• A strong accessory is available from a certain bookshelf in the final chapter if you have read every book on the bookshelves (or more likely, spammed confirm through them) before the final chapter.

• Everyone will participate in the final dungeon, so it's best to occasionally make sure your party members are keeping up level-wise. XP scales so that party members who are behind can catch up fairly quickly, but there is still a cap of 9999 XP gained per battle no matter how many thousands of XP behind they are.

• Along that line, the more sepith you can accrue the better, to get as many high-quality quartz as possible. It won't be possible to try to game the system by only equipping one team.
