The Seraphim leaps into battle, inflicting damage when she lands in her target area. In critical situations, this jump may also be used in order to escape.
Impetus - Inflicts damage not only on the target but also on nearby opponents. (~2.25m area of effect)
Gold
Bewilder - The seraphim leaps away, briefly reducing the run speed of opponents at her starting location. (1-1/(1+(500+5*calvl)/1000) percent reduced movement speed; ~33% at CA-Lvl 1, ~35% at CA-Lvl 10, ~43% at CA-Lvl 50 (guess))
Concussion - Chance to stun the target. (15% + 0.1% per CA level chance)
Tactics Lore - indirectly, it increases weapon damage and critical chance, thus making Assailing Somersault hit harder, also allows modification points.
Any weapon lore (such as Sword Weapons when the Seraphim is wielding a sword) - will indirectly increase this combat art's execution speed, damage and chance to hit, and will allow the equippng of higher level weapons used to execute this combat art.
Concentration - will lower this combat art's regeneration time.
Combat Discipline - will increase the damage of this combat art and lower its regeneration time if it is placed in a combo. This increase in damage is direct; it increases the +xx% that the CA adds to base damage.
Speed Lore - will increase its chance to hit indirectly by increasing a player's attack rating.
Silver mod Impetus is a good choice because it will transform in Assailing Somersault into an area-of-effect CA that damages multiple opponents.
