Secondary professions for a Paragon

Paragon/Warrior

 * "For Great Justice!" is an unlinked non-elite alternative to Focused Anger, which can be useful to get adrenaline.
 * Shouts such as "Watch Yourself!" are effective for energy management and triggering echoes and "chorus" chants.
 * "Coward!" can be used with the fast adrenaline gain of the Paragon.
 * Combining Warrior shouts with Paragon chants can create extremely effective support.

Paragon/Ranger

 * Animal companions can be useful in smaller teams to utilize higher leadership energy gain potential.
 * Nature Rituals can be useful with Paragons attacks and adrenaline, but can be created by another ally instead.

Paragon/Monk

 * Balthazar's Spirit is sometimes used on an Angelic Bond Paragon.

Paragon/Necromancer

 * A few Paragon skills inflict conditions on yourself; Plague Touch, 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.

Paragon/Elementalist

 * Conjure Flame and other conjure spells can work well with a spear, certain skills that trigger or cause burning can also be synergistic
 * For example, Conjure Flame and Mark of Rodgort combined with a Fiery Spearhead causes almost constant burning. This also works well when combined with AoE Elementalists.
 * 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

 * Shadow Arts provides placement skills that can be useful in conjunction with shouts/chants.
 * Deadly Arts offer specialized skills for a specifically tuned offensive Paragon.

Paragon/Ritualist

 * A Ritualist hard res (Death Pact Signet or Flesh of My Flesh) may be preferred over the low heal and slower cast time of Signet of Return.
 * Vocal was Sogolon is an item spell designed particularly for Paragons, extending the length of shouts and chants.
 * 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.

Paragon/Dervish

 * Ebon Dust Aura can be a very useful skill for a Paragon to spread blind around.
