Iterative attack
Iterative attack is an umbrella term for the skills second attack, third attack, and fourth attack. A character with these skills will occasionally attempt to make a second/third/fourth attack in each round of combat, with the chance of making each attack rising with mastery of each subsequent skill. Many martial classes have skills that alter or impact the usage of iterative attacks.
Fighters
Fighters possess all four attack skills, and passive skills such as Kalysian cunning, reach mastery, and a hidden but built-in chance of successful iterative attacks. Kalysian cunning means that a fighter who has mastered second attack is almost certain to get two attacks each round, while reach mastery aids in not losing further attacks to group mischief.
Swordmaster
Swordmasters possess all four attack skills, as well as forms that impact iterative attacks such as Mongoose, Reed, and Whirlwind. Form of the Reed prevents a Swordmaster from making iterative attacks beyond the first, while Form of the Whirlwind allows a swordmaster to attempt iterative attacks against all opponents.
Gladiator
Gladiators possess all four attack skills, and the passive corner and enthusiasm skills. Gladiators excel at fighting multiple opponents, their corner skill allowing them to attempt full rounds of attacks against every opponent while enthusiasm means that each blocked attack increases a gladiators chance of a successful attack.
