Like all Tales characters, Legretta has her own set of artes that she can use while in Somarium.
First it should be noted that her weapons are twin handguns. However, they do not fire bullets. They fire fonetic energy. Fonons are something from her world and it's easier to just think of them as a different sort of energy source. This allows her to pretty much have unlimited ammo and fire quickly. So whenever someone is shot by her, the damage is more like a beam of energy that goes through them while still inflicting the wound. Laser gun. Simple as that.
She is also adept at using daggers and the staff/spear at least, as she was the one to teach Tear how to use such weapons. She is also good at martial arts in general, as well as quick. In the game, she has a ridiculously high defense, so in RP terms, I'm going to alter that so it just means she has high endurance and take a beating as well as blocking and dodging.
Also, Legretta's element is Light, meaning any light based attacks are ineffective. She also can perform her high leveled artes without the need of an FoF that other Tales characters normally need.
ARTES
Rage Laser
⊗ Basically shoots large laser beams out of the guns.
Searing Sorrow - "Burn! Searing Sorrow!"
⊗ Summon a meteor which crashes at the target and creates a giant pillar of fire.
Inlay Nocturne - "Begone! Inlay Nocturne!"
⊗ She fires her guns and a yellow crystal appears. With a swipe with her gun it explodes.
Ressurection
⊗ Able to revive the fallen.
Eclair d'Larmes
⊗ light elemental (50% FOF) fonic arte. It stamps a rune on the ground that blasts the target with light. It's an area effect skill, so she can target more than one person
Holy Lance
⊗ light elemental (100%) fonic arte. Basically shoots down a lance of light on enemies. Area effect.
Blessed Drops
⊗ water elemental (100%) fonic arte. Drenches a large area of the battle field in water.
Flamme Rouge - "How do you like this? Flamme Rouge!"
⊗ FOF activated by using Eclair d'Larmes in a Fire or Light FOF circle. Basically the same as Eclair d'Larmes only using fire instead of light. FOF NOT REQUIRED
Cluster Raid
⊗ A beam of energy above the target area sends up spikes that impale,
then the entire area explodes. (FOF activated by using Holy Lance within an Earth or Dark FOF circle.)
Divine Saber
⊗ light elemental fonic arte. Unknown :\
MYSTIC ARTE
Like all other Tales characters, Legretta has her own Mystic Arte.
Prism Ballet - "O fragements of light, strike down mine enemy! Prism Ballet! This ends now!"
Basically there is an explosion of light beams around her while she also lets loose a large show of gunfire before finishing off with an attack similar to Rage Laser.
