Secondary professions for a Paragon

Paragons gain an near infinite amount of energy from spamming low-cost (be it adrenaline or energy), low-recharge shouts and chants. This means Paragon secondaries are usually used for higher costing, moderately or low recharging skills or lower costing, near instantly recharging skills all of which don't need a large amount of attribute points to be effective with. This is because Paragons already have to allot a large percentage of their attribute points between leadership, which gives them that million energy, command or motivation, which gives them their shields, and spear mastery, which gives them their weapons and their attack skills for outputting damage.

Paragon/Warrior

 * "For Great Justice!" is an unlinked non-elite alternative to Focused Anger, which can be useful to get adrenaline. When using both simultaneously, with enough ranks in leadership, a player can have double the adrenaline in PvE permanently (but not PvP due to the nerfs).
 * Shouts such as "Watch Yourself!" are effective for energy management and triggering echoes and "chorus" chants but the shout itself got nerfed making it much less useful.
 * "Coward!" can be used with the fast adrenaline gain of the Paragon.

Paragon/Ranger

 * Nature Rituals can be useful with Paragons attacks and adrenaline but should be created by another ally instead.

Paragon/Monk

 * Balthazar's Spirit is sometimes used on an Angelic Bond Paragon but Angelic Bond has been nerfed heavily since its inception.
 * With the high energy gain of Leadership, certain maintained enchantments such as Strength of Honor can be maintained on frontline characters with almost no negative consequences to the paragon.

Paragon/Necromancer

 * Rend Enchantments can be used in PvP to provide prepping for a spike.
 * Blood is Power is sometimes used on Paragons in PvE and very rarely in specialized gimmick builds in PvP to help midline and backline casters in managing their energy pools.
 * A few Paragon skills inflict conditions on yourself; Plague Sending or Plague Signet can be used to transfer these conditions.

Paragon/Mesmer

 * Expel Hexes and Shatter Storm are often used in PvP.
 * Mirror of Disenchantment can be used in PvP to debuff Aegis or Conjures. Good teams with multiple conjures always alternate them however: one person takes Conjure Flame, the second takes Conjure Lightning, etc.
 * Power Return is often used as a fast recharging interrupt in both PvP and PvE.

Paragon/Elementalist

 * Conjure Flame and other conjure spells can work well with a spear, buffing DPS slightly.
 * Shell Shock with Chest Thumper can also be used for a good combination. (Usually coordinated PVP)
 * Combining Shock with Awe creates an easy one-two combination leaving you able to decimate casters before they can sync into a rhythm. With the correct distribution of attribute points, dazed can be kept up indefinitely.

Paragon/Assassin

 * Deadly Arts offer specialized skills for a specifically tuned offensive Paragon.

Paragon/Ritualist

 * Vocal was Sogolon is an item spell designed particularly for Paragons, extending the length of shouts and chants. Most of the chants that it worked well with however, such as "Incoming!" have been nerfed due to the overpoweredness of this combination.
 * Splinter Weapon is a weapon spell that can be effective with spear mastery based Paragons, causing splash damage to enemies surrounding the target foe, Brutal Weapon can be used to boost damage output (much like Conjure element for the P/E but without risk of disenchantment), and other weapon spells enhance the abilities of an offensive Paragon. Splinter Weapon, however, is better placed on a caster that isn't attacking all the time so the paragon can get the benefits of the weapon, such as an ally.

Paragon/Dervish

 * Ebon Dust Aura can be a barely useful skill for a Paragon to spread blind around except that it is done far better by a ranger using Volley and Paragons have better defensive skills of their own.
