Secondary professions for an Assassin

Assassins are highly aggressive, focused damage dealers, better for hit and run skirmishes then drawn out tanking or back-line sieges.

Always remember, when choosing secondary skills, that native skills often have better synergy with the profession's purpose, interact better with the profession's other skills, and benefit from runes.

Assassin/Warrior

 * Assassins do not have any attack speed enhancing skills (Excluding the PvE/Nightfall-only Critical Agility). Flurry, and Tiger Stance can increase the rate they can pull off an attack chain, as well as increase their overall DPS.
 * Wild Blow requires no attribute points. It cancels the foe's stance, cannot be blocked, and causes a critical hit, which renews skills such as Critical Defenses.
 * Daggers' ability to double strike allow massive use of adrenal skills like "Fear Me!".

Assassin/Ranger

 * Barrage damage can be improved with high critical strikes attributes, adding bonus damage to attacks, energy management, and effects from skills like Critical Eye, if you use Barrage with Sharpen Daggers, you can also spread bleeding.
 * Serpent's Quickness can help keep enchantments such as Heart of Shadow and Critical Defenses at the ready.

Assassin/Monk

 * Monk skills have no specific synergy with Assassins, see the Monk entries in the for all professions and for melee professions sections of general secondary professions for more general information on Monk as a secondary profession.

Assassin/Necromancer

 * Assassin and Necromancer Skills have very little synergy.

Assassin/Mesmer

 * Arcane Echo can be used to chain Shadow Form when running or soloing.

Assassin/Elementalist

 * Shock can knock down foes quickly, which combines well with skills such as Falling Spider.
 * The Conjure Lightning, Flame, and Frost spells can massively increase the assassins DPS.

Assassin/Ritualist

 * Sparing use of weapon spells such as Warmonger's Weapon can aid an Assassin in battle, although weapon spamming is best left to Ritualist primaries.

Assassin/Paragon

 * "Go for the Eyes!" is the only Paragon skill which has good effectiveness with Assassins due to increasing chance of a critical hit.

Assassin/Dervish

 * Critical Strikes used in conjunction with a scythe can create massive critical hits.
 * Some Dervish enchantments can help the Assassin survive longer in battle, or increase damage output.
