Capability 1:

First Strike - When an assassin enters a battle, he gains a 50% bonus to all physical damage he deals. This bonus persists until the first time he takes damage in the battle, which will break his momentum. (Passive Ability)

Capability 2:

Weapon Mastery - Any improvised weapon wielded by an assassin assumes an attack value equal to that of his primary weapon. An assassin may also throw any weapon without incurring the Hit SVS penalty. He may even throw weapons he is unable to wield. Once per battle, an assassin may attack with a weapon that he has just parried with; the base damage dealt by this weapon is doubled for this attack. (Utility Ability)

Capability 3:

Swift Steel - An assassin is able to make a parry attempt against any physical attack, even if his opponent is using an ability that declares his attack unable to be parried. The assassin can parry even if his Total STR PVS is less than half of his opponent’s. Twice per battle, an assassin may make a parry attempt against a force attack and will knock it away with his blade on a successful attempt. (Utility Ability)

Capability 4:

Follow Through - If an assassin dodges or parries with a roll of 91+, any attack he makes this turn deals a bonus 20% damage. (Passive Ability)

Capability 5:

Copy Cat - If an assassin makes a successful physical strike against an opponent who had inflicted a negative status effect on the assassin in his last turn, then the recipient of the assassin’s attack gets a taste of his own medicine and receives an the same status ailment. The intensity and duration of this copied effect is identical to the original. (Passive Ability)
