Secondary professions for a Ritualist

Ritualist/Warrior

 * This profession combination is relatively unbeneficial, apart from a few Underworld farming builds.

Ritualist/Ranger

 * Nightmare Weapon can be useful when used in conjunction with Dual Shot and Forked Arrow for a large, unprotectable life-steal spike.
 * Weapon spells like Splinter Weapon and Warmonger's Weapon synergize well with Barrage, but this is more commonly used on a Ranger/Rituatlist.

Ritualist/Monk

 * Ritualists lack hex removal skills, and can benefit from the expanded condition removal from monk skills.
 * Attuned Was Songkai can be used to lower the cost of expensive spells that have quick recharge times for a great effect.

Ritualist/Necromancer

 * Spawning Power makes undead allies that have good survivability, but generally have less damage and lower armor due to the lack of Death runes. (see the general minion mastery guide for more information.)
 * Explosive Growth is a useful way to add damage when summoning minions, particularly with Animate Bone Minions.
 * Spirit's Gift is also good to use while summoning minions as it will help keep your team alive as well as your minions.
 * Boon of Creation assists greatly with energy management, as it affects minions as well.

Ritualist/Mesmer

 * Arcane Echo can be used to increase the damage potential of channeling builds and Ritualist farming with Vengeful Was Khanhei.
 * Mantra of Concentration or Mantra of Resolve can be used to protect against interruption.
 * Mesmers have several cheap anti-Hex skills that can make up for the Ritualist's lack of hex removal skills, such as Expel Hexes, Revealed Hex and Inspired Hex

Ritualist/Elementalist

 * Glyph of Lesser Energy is useful in reducing the cost of your more expensive spells.
 * Glyph of Swiftness can help upkeep skills like Attuned Was Songkai.
 * Several skills increase spiking capabilities. Like Aftershock following Grasping Was Kuurong.

Ritualist/Assassin

 * A player may not Shadow Step while holding an item. In this way a Ritualist can bomb targets by using a recall skill and forcing the item they are holding to automatically drop.
 * Daggers can strike more often than any other weapon in the game due to the Assassin's chance to double strike. For this reason, combining dagger attack combos with weapon spells and Spirit's Strength can cause a lot of damage.

Ritualist/Paragon

 * Spirit's Strength combines well with spears, since their faster attack rate makes for a decent ranged weapon. Adrenaline-based spear skills also help to keep a continual flow of energy open for maintaining your enchantments and weapon spells.

Ritualist/Dervish

 * The elite skill Spirit's Strength works well with scythe attacks due to the AoE effect of scythes.
