The BoA Sin (also called Burst Sin) is a fragile yet very deadly assassin used to take down targets quickly while making use of Shadow Prison to snare the target long enough to unleash the build's vicious assault.

Equipment
A Full Set of Radiant (insignia) armor.
Zealous, Vampiric and Ebon Daggers of Fortitude.
Usage
The spike is done quickly, in the following order:
Shadow Prison -> Burst of Aggression -> Black Lotus Strike -> Twisting Fangs -> Black Spider Strike -> Blades of Steel.
Execute the attack chain with Vampiric daggers.
Switch to Zealous daggers if energy runs low.
Use Ebon daggers when fighting a Warrior or when you are not engaged in combat.
Use Expose Defenses if your target is protected by any skill (Aegis, Guardian, Weapon of Warding, Ward Against Melee) that gives a chance to block attacks.
Counters
Standard Melee counters.
Restore Condition will basically ruin a spike of this build, it'll remove all of the conditions you have put on the target and heal most of the damage dealt.
Hex Breaker will cause problems, as your initial 'Hex Jump' will be disabled, leaving your combo in shambles unless you can cast both hexes in quick succession.
A well-used Contemplation of Purity.
Variants
Horns of the Ox is a common variant that sacrifices damage for a knockdown, and can therefore replace Blades of Steel.
Another Shadow Step or an additional healing/defensive skill (such as Feigned Neutrality) can replace the Resurrection Signet for Alliance Battles or Competitive missions.
Siphon Speed can replace Expose Defenses as a backup hex to trigger the attack chain, and to quickly escape.
Impale can be used in conjunction with different dual attacks (Horns of the Ox in Particular).
Death Blossom can replace Blades of Steel.
Assassin's Promise and Dark Prison can be used as a more PvE or AB/CM oriented version.
