So there has been little definitive discussion regarding the mechanics of New Game +, specifically what carries over and what's newly available. Wanted to create this quick reference to pitch in what I've discovered so far and help shed some light where possible.Changes:Saint Statues: Right off the bat, the primary difference between a regular playthrough and an NG+ run is that the bonuses you have previously unlocked from upgrading statues are permanent and will carry over. They do not have to be re-purchased using renown, as it has been established that it is not possible to fully upgrade all four in a single playthrough. These upgrades will remain permanent for every subsequent playthrough, and will never have to be re-purchased so long as you are playing on the same File chain. The total amount of Renown required to fully upgrade all 4 statues is 40,000 Renown (10,000 each)The Ability to Purchase Previous Supports: You will have the option of purchasing Supports that you unlocked with characters in previous playthroughs as long as said characters are available to interact with. They are not unlocked by default once purchase, meaning they will need to be re-purchased in every subsequent run. As an example, my Blyeth attained an S-Support with Dorothea on my first run, thus it was possible to immediately purchase Supports from C-S for Dorothea on the first New Game + using Renown. On a second playthrough, if your Blyeth S-Supports a different character, say Edelgard, then on every future NG+ playthrough, both Dorothea and Edelgard will have their C-S Supports immediately available for purchase. The exchange rate for one level of Support is 400 Renown for every level, so one full S-Support is a total of 1600 Renown.The Ability to Immediately Upgrade Professor Level: It takes a total of 4500 Renown to fully upgrade to A+, which will allow Blyeth an immediate 10 Activity Points on each Explore day. It is NOT recommended that you fully upgrade right from the beginning, as doing so will prevent Blyeth from earning Renown from activities that would normally raise their Professor level, such as eating meals.The Ability to Purchase Skill Levels, Combat Arts, and Abilities: These need to have been previously unlocked on a specific character from a previous playthrough in order to be available for purchase, i.e., if a Felix from a previous playthrough attained an A+ Skill Level for Sword (regardless of which of the four routes you recruited him) you will have the option of immediately purchasing an A+ Skill Level as soon as you have Felix in your roster, much like Support. As with Supports, all previously unlocked Skill Levels, Combat Arts, and Abilities on ALL runs will be available on subsequent playthroughs, but the unlock will still be specific to the character (i.e. unlocking a skill for one character on a previous playthrough does not make that skill available for Renown purchase on another in NG+)All Previously Hired Battalions Remain in Inventory: Battalions that you acquired in previous runs will be immediately available in your inventory from the start of NG+. By extension, all battalions you had in your first and second playthrough will be available in your third, and so on. These are availble from the start, and do not need to be re-purchased.Shop Items: All unlocked Shop Items from your first playthrough will be immediately available on every NG+ run. This includes items that are typically stocked in limited quantity, which will still retain their monthly limit. Prices do not change for items, and specific shops (such as the Battalion Shop, Eastern/Western Market, etc.) must still be unlocked with their specific conditions (certain day, completing the relevant quest, etc.)Crests: Upon completion of your first playthrough, several Crest Items will be immediately available in the convoy for use. These have various in-battle abilities for you to use on subsequent runs as long as your character has it in their inventory. The specific crests allocated vary depending on choices made during your previous playthrough, although it is currently uncertain what specifically determines the Crests you are given.Appearance: You will be able to switch each character's outfit from their Student Outfit to Post-Timeskip Outfit. The three main lords also have an additional option of changing their hairstyle, should you so desire.Acquiring Renown:The amounts of Renown rewarded for typical activities are as follows:Quests on Exploration Days in the Monastery: 200-500 depending on questCompleting Battles/Quest Battles if Battle option was selected on Sunday: 100 per Battle if Blyeth is MVP (this does NOT include battles on normal mode that do not require Battle Points and can be infinitely farmed)Completing Monthly Missions: 100 per Mission only if Blyeth is MVPThat's all for now; will update as more is discovered along the way.
