Here’s a small guide for those looking for a little more information than the game would like to provide~
The game determines the available endings based on the number of times you have seen heart events with the characters per game (regardless of actual heart levels), so to make the most number of endings per playthrough possible, limit the conversations to a maximum of 2 per character (of course, this would mean that you’ll be restricting your tension skill level, so the best time would be after the first completion).
If you’re after an enemy item, you can make a quick save, then perform the kill and observe if an item is dropped. Retreat to see if you get what you want, and if not just exit to the title then restart from right before the kill – the result will be different each time.
The best way to go about getting that achievement is to craft and equip the Crystal Upsurge ability, from a Brass Mask (dropped by low level tin troopers) and a Magnetite Ore (which you can buy). Alternatively, using the Alkaline Salts bath salt and resetting for the Crystal Upsurge benefit does the same thing.
New Game Plus
Considering you can only bring along 5 items but get to keep all your crystals, be sure to sell the rest before finishing the game, and throw as many skills/abilities as possible on the characters you’re bringing over to the new game, as they get carried over as well. Items under the ‘Other’ subsection are automatically carried over, so you only have to choose between the rest.
If you notice from time to time when you speak to characters they might ask you to exchange items. There is only one miss-able trade, which is for the Innocent Wish skill (and achievement) that requires the Mystery Capsule to be traded to Bart in the final chapter. If you instead choose to trade it to Beatrix, then you will have to craft it. If you are on your second playthrough or more and bring over a Fool’s Medal, you can then trade it to Bart for an AP Regen +2 in Chapter 3.

Successfully crafting the two will unlock both hidden achievements (save before crafting as abyss fragments have a chance of failure). Both skills can also be obtained by trading items to characters within the game, but just remember not to trade the Mystery Capsule to Beatrix if you want Innocent Wish. Merciful Heart can be gotten in an exchange after you obtain the jade brooch in a trade once you start a new game.
