Rozalin - Gun Toting Love Interest
Rozalin is a playable character in battle. What's more, she is the there from the very beginning, and will not leave your party unless you get that one bad ending where you have to fight her in her Zenon persona.
Rozalin stated from the very beginning that she has zero battle experience, as her servants have done everything she needed for her. After the tutorial battles, she gets the hang of things.
Rozalin's special passive ability in combat is that when she stands adjacent to any male humanoid (monster classes do not count), their powers and stats are boosted (a 20% stat increase to all adjacent male units, not just one). It's typically a good idea to keep her behind Adell (who may be your most powerful male unit), especially since her weapon of choice is long ranged.
Speaking of her equippable weapons, she can equip anything. The only differences are the mastery rates, which also increase power and skills. Obviously, the gun is her default weapon because it's the best one for her. The Gun is at a Mastery Rate of 24; the next highest mastery levels of weapons for Rozalin are the bow and the staff at Mastery Rate 18.
Guns rely on the HIT stat for attack power rather than ATK or the other stats, which works for Rozalin because pumping up her HIT state with accessories and the like is a lot easier than trying to pump up her ATK stat, for instance. The ATK aptitude for Rozalin is only 80%, while her HIT aptitude is 120%.
On an added note, Rozalin's Lover Bonus is 1% per specialist level.
Rozalin's unique attacks include Rose Thorns>, Kneel Before Me, and Rose Liberation. Rose Thorns is learned at Level 5, and is an attack that is fixed with Rozalin's locations. The three panels in front of her three panels away are the target, where Rozalin takes out a gatling gun and unleashes her fury on enemies. It's a rather weak attack, but it's useful in a chain if needed. Its power depends on Rozalin's HIT stat, and consumes 24 SP.
The second special skill, Kneel Before Me, is a support skill. It affects a three-by-three "+" shaped area within a certain range of Rozalin and is not fixed by her location. It increases the ATK, HIT, and INT stats of allies affected by it by 10%, and is learned when Rozalin hits Level 25, and consumes 20 SP.
The third skill, Rose Liberation, is Rozalin's most powerful unique special ability. It is learned at Level 50, and uses her HIT stat to determine damage output. It is learned at Level 50 and consumes 90 SP. It, like the previous skill, affects a "+" shaped area within a specific radius of Rozalin, and its position is not locked with Rozalin's position. Rozalin jumps up into the air, and gathers a giant ball of dark energy, whcih is then hurled toward that enemy group. The true Overlord Zenon has a variation of this attack, called Dark Liberation.
Gun abilities include Tri-Burst, Gaia Blast, Proximal Shot, Shooting Stars, Totenkreuz, and Inferno.
