I am playing P3 FES for the first time ever. I played and beat Persona Golden on Vita almost two years ago but I never jumped into P3 ever. Playing it on ps3 right now. Any tips for me as I jump in?
Because of all the things you're able to do, if you don't budget your grinding vs stat-building and s-linking, the earlygame can be very difficult when you get underleveled. Likewise endgame might have little to do since you did all the stat-building too early in the game.
Because you can't directly control allies, it may become somewhat inconvenient because in certain fights they won't do exactly what you want. For example, on Act Freely, they will not heal you until you're rather low on health, so you'll have to manually set them to heal/support if you want to be safe. But on the off chance that there's nobody that requires urgent healing, they might heal someone who has enough health but is slightly damaged, etc. instead of something that you might think would be a better use of a turn. Really only a problem with specific cases.
When downed, the enemies lose their chance to act, and actually get back UP if hit again. This means if you hit an enemy's weakness they'll get downed, and when it's their turn they waste it getting up if they're still downed by that point. This allows you to take down enemies without letting them take any turns since they spend every turn getting up. Unfortunately, the same can apply to you, I personally took unlucky crits a couple times and as a result I lost a couple turns unable to do anything. This may be annoying in random battles since if the enemy moves first you can get crit/hit with a weakness and lose your turn without setting any tactics for your allies.
Compared to Golden, the gold shadows are alot less useful (no exp), so it's not really much worth farming for. They can give special weapons where you fuse a persona into it and it gets special properties (if they do drop the item, you won't get any money), and they might give you items that sell for a lot, but that's all. If you need to, you can go to floors where the shadows run away from you since you're higher level than them, then set the orders to split-up, and use your allies to grab chests for items, money, and equipment. Then can rinse and repeat.
For the dungeon, shadows cannot chase you / detect you if you're on stairs or higher elevation, so you can use that to your advantage for first strike. Also, you can pause then unpause, and immediately after the shadow will turn (unless you're already detected), so you can do this trick to get shadows to turn around until you have them facing the way you want for player advantage.
I think dark/light skills do not get more accurate if they enemy has a weakness to it, all you get is another turn if you hit it. Could be wrong though, but that's from personal experience.
Think that's all I can think of, probably a lot more tips though.
