Cross profession ability combos.

GW2 skills from different professions that will combo with each other, granting one or both skills additional effects when used in combination. The biggest example we've seen is Elementalists or Rangers can plant fire on the ground, which will then give friendly arrows that pass through the flames additional fire damage. Here are some of my own ideas for spell 'combos', using the known list of GW2 skills.

• Combo name: Flock's Feast
• Component A: Hunter's Call (Ranger)
• Component B: Deathly Swarm (Necromancer)
• Effect: When a Necromancer casts Deathly Swarm on a target afflicted by Hunter's Call the birds will follow the insects to a secondary target as they bounce, refreshing the duration timer on Hunter's Call.

• Combo name: Magnetize
• Component A: Lightning Bolt (Elementalist)
• Component B: Spread Shot/Splitblade (Ranger)
• Effect: After being hit by Lightning Bolt a target will become magnetized for a short time. A ranger that casts Spread Shot or Splitblade in a direction that would hit a magnetized target will find that the projectiles arch towards the magnetized target, hitting it with each projectile, doing max damage to a single target, and then continuing to fly in their spread pattern away from the ranger, with their point of origin at the magnetized target, hitting anything standing behind it.

• Combo name: Lightning Rod
• Component A: Devastating Hammer/Stomp (Warrior)
• Component B: Lightning Bolt (Elementalist)
• Effect: Devastating Hammer and Stomp launch a target into the air. While the target is in the air Lightning Bolt is guaranteed to crit (and have a bigger meaner animation).

• Combo name: Sandstorm
• Component A: Dust Trap (Ranger)
• Component B: Tornado (Elementalist)
• Effect: An Elementalist in Tornado form that passes over a friendly Dust Trap will change color to be more yellow/brown, and now blinds in addition to knocking enemies back.

• Combo name: Blood Frenzy
• Component A: Blood Fiend (Necromancer)
• Component B: Any bleed effect
• Effect: The more bleeds stacked on a target, the faster the Blood Fiend will attack that target.
