Secondary professions for an Assassin

Assassins are highly aggressive, focused damage dealers, better for hit and run skirmishes than 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

 * Flail is useful for increased attack speed for assassins, if they can build up adrenaline beforehand (And if they have a cancel-stance for catching fleeing target)

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.
 * Disrupting Accuracy in combination with high critical strikes and skills like Way of the Master and/or Critical Eye make nearly every shot an interrupt. Combine with IAS for even greater brutality.  Keen Arrow also synergizes with the assassin's high crit rate well.

Assassin/Monk

 * Assassins can take self-heal skills such as Live Vicariously and Vigorous Spirit with Critical Defenses to provide decent self-heal and survival.

Assassin/Necromancer

 * This profession combination provides very little bonus for primary Assassins.

Assassin/Mesmer

 * This was originally used for permanant Shadow Form assassins, but is inferior to the A/E Glyph of Swiftness permanant Assassin.

Assassin/Elementalist

 * Shock can knock down foes quickly, which combines well with skills such as Falling Spider.
 * Conjures can be used to trigger "Golden attacks"
 * Glyph of Swiftness can be used to reduce the recharge of Shadow Form to an infinitely manageable skill.

Assassin/Ritualist

 * Weapon spells (such as Warmonger's Weapon) can aid an Assassin in battle and are immune to disenchantment.

Assassin/Paragon

 * A spear-wielding Assassin with a high critical strikes attribute and skills such as Way of the Master and Critical Eye will be able to deal substantial damage, due to a spear's fairly high maximum damage and Vicious Attack.
 * Even with no points in Command, "Go for the Eyes!" provides a significantly higher chance to land a critical strike.

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.
