Secondary professions for a Monk

Monks are almost exclusively party support characters, and do not benefit from most of the hostile skills from other professions. Healing and protection Monks often use their secondary profession to benefit from energy management or self-defense skills.

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.

Monk/Warrior

 * During PvP many monks will often use a shield for defensive bonuses from mods. Consider the skill Shield Bash when using this tactic.
 * Balanced Stance is useful to protect against various Knockdowns, as well as preventing damage generated by Critical Attacks.
 * Several stances allow Monks to prevent being spiked, using instant-activation time and block bonuses when targeted.

Monk/Ranger

 * A Monk/Ranger is also one of the best running combinations for the Southern Shiverpeaks. Ice Imps and Ice Golems pose no threat when using Spell Breaker, which can be held up most of the time by using Serpent's Quickness. The ranger speed boosts ensure that running past the enemy is swift and harmless.
 * Stances can be useful. Melandru's Resilience often offers great synergy.  Block stances can be good, but not necessarily as good as a Mo/W.  Movement stances can be good, but not necessarily as good as a Mo/A.

Monk/Necromancer

 * Offering of Blood can be used to provide energy management.

Monk/Mesmer

 * The Inspiration Magic line provides a variety of energy management skills.
 * Channeling is often used in Heroes' Ascent, in combination with spammable 5 energy cost skills.
 * Inspired Hex not only removes a hex from a target ally, but it also gives the player energy.
 * Ether Signet is an alternative choice that gives you a boost of energy when you are close to 0, however this is hampered by a very long recharge.
 * Hex Breaker is useful to preemptively protect against hexes in PvP.

Monk/Elementalist

 * Glyph of Lesser Energy offers energy management for the monk.
 * Glyph of Concentration can be used to counter daze.
 * Storm Djinn's Haste is used in GvG matches to run flags.
 * Though not nearly as useful as Return, Grasping Earth can snare foes and allow easy kiting.
 * Earth Magic can help a monk not be so "squishy". In addition to things like Armor of Earth, Obsidian Flesh can be kept up a greater percentage of the time than Spell Breaker, and Stoneflesh Aura is in many ways better than Shield of Absorption.

Monk/Ritualist

 * This profession combination provides little benefit for a Monk primary. Ritualist skills do not benefit from Divine Favor, and most protective or healing effects provided by Ritualist skills are easily outpaced by native Monk skills.

Monk/Assassin

 * Shadow Arts skills such as Dark Escape for protection from melee damage dealers. Especially useful is Return, which cripples enemies while teleporting you towards an ally.

Monk/Paragon

 * A Mo/P often will be seen using skills such as "Brace Yourself!" or "Make Haste!" to buff Party members. Though not as commonly seen, Mo/P's sometimes come in pairs to buff each other.
 * Many of the protective and healing effects provided by Paragon skills can be better replicated by native Monk skills.
 * Motivation can be a good combination with Monk healing spells

Monk/Dervish

 * Skills such as Conviction and Vital Boon help to keep the Monk alive in PvP.
