Magichange is gone
[*]Monster weapon type is gone and monsters use regular weapons
[*]Toss and pass are gone, and in their place monsters can lift and throw
[*]Weapon skills are gone; in their place are unique skills that each class has, many of which are derived from old weapon skills (Zielregen, Boulder Crush, Totenkreuz, Triple Strike, etc)
[*]Traditional stat buff spells seem to be gone, with unique buffs (like the healer's damage buff or thief's self-SPD/HIT buff) taking their place
[*]Equipment aptitudes are gone
[*]Chara world is gone (thank god) with its stat-boosting and evility scroll-making functions relegated to super reincarnation and the skill shop respectively (generating skill scrolls does not seem to exist anymore)
[*]In addition to generating evility scrolls, the
[*]Many classes are gone, even long-runners like nekomatas
[*]Tower skills are gone
[*]Revenge meter, squad attacks, and Overloads are gone
[*]Interrogation is seemingly gone: squads are leveled with EXP and mana gains from battle
[*]Classic-style capturing is seemingly gone
[*]Innocent management, farm included, is handled with the item worlder again
[*]The new "innocent exchange" submenu of the item worlder allows you to spend item points to acquire innocents
[*]Enemies in the item world seem to have randomized resistances again
[*]Enemies in the item world seem to always have a bunch of spells learned, of all elements (plus healing)
[*]Innocent town is still a feature, but routes are not
[*]Mystery gates are back
[*]Pirates/invaders don't seem to be present: I haven't encountered them yet and the tutorial says nothing about them
[*]Innocents aren't "true neutral" like they were in 5 and actually will fight both the player and the enemy
[*]Lucky boards have actual AI and can attack you
[*]The stage doesn't end until all lucky boards are defeated; I'm not sure if this holds true for neutrals like level spheres, chests, or innocents
[*]The recruitment NPC is gone and that function is handled by the assembly again
[*]The hospital NPC at the base map no longer provides healing, as auto-heal is now a default mechanic; he simply gives you rewards for the amounts recovered

[*]Item exploration replaces netherworld exploration
[*]Enemies can actually use the archer's support attacks now, which totally surprised me

[*]You can't stand on geo symbols or level spheres anymore
[*]The item duplication mystery room seems to be still present and even has the same layout, but it's been visually overhauled
[*]Bonus meter is different: extra levels don't seem to be present, equipment seems a lot more rare, and the rank-0 item isn't forfeited when the floor is skipped
[*]Getting to the gate at the end of a floor will reward you with a level, like in the pre-5 games, regardless of meter
