I finally received the game a few days ago and after my first week back at Uni, I've just now found the time to give it a go. Does anyone have any suggestions or tips for someone completely inexperienced with the game and franchise in general? This is my first SMT game and I was expecting a difficult learning curve but not to this extent. I've already seen my party wiped several times, the latest by a Horde of some kind that seemed to come from nowhere.
Pay attention to elemental weakness and resistances. This game has no resistance stat, so everyone, both playable characters and enemies, are glass cannons who can fall in a few hits. Hitting elemental weakness also gives you (or the enemies) extra turns. On the other hand, missing attacks, or attacks completely blocked/reflected due to elemental resistances make you lose your turns. Skills with low hit rates generally aren't worth it due to the danger of missing attacks. Critical hits (which can only happen with physical attacks) also result in extra turns. However, if an attack results in extra turns and missing turns (like a multi-hit attack that criticals once, but misses another foes), it seems like only the missing turns count.
Also, Rakujaka (raises defense) and other stat boosting or lessening spells can be used up to three times (press X to see the active bonuses) and they can be very important in boss battles).
I'm also having a lot of trouble recruiting demons; most seem to take my items/macca and then leave.
When you attempt to recruit demons, ending the conversation after giving three gifts often works. Also, eliminate the other ones and leave only one demon around when you attempt to negotiate in case it attempts to attack you. Don't get attached to the demons, fuse them often to get stronger ones. Only in later levels you'll get demons that are good enough to keep around for a long time.
For early game, Llham Dearg might be useful and could be kept around for a while, as long as you aren't facing ice using enemies. He has resistance to physical and shooting, which should help a lot early on - aside from the battles with ice enemies, due to his ice weakness. He has a multi hit skill with low hit rates though, so remember that you might end up losing turns if he uses it and misses even one hit. Keep track of your own armor too.
The free DLC white samurai coat has good stats that can last you almost half of the game, but it has an ice weakness, and you'll face a horde of ice opponents fairly early on, so remember to remove it if you die there once and attempt to face them again. On the other hand, your initial samurai coat is ice resistant, so you should be wearing it while going to that battle, even if you'll lose some stats due to it. Equipment stat boosts here are small enough that you'll want to focus more on the resistances and weakness of the chest piece rather than raw stats.
