In the same way some effects from weapon are Melee and proc Swift Flurry, some others are Ranged and proc Driving Flight. Even if the most of weapon effects work fine with the Ring of the Marksman, Strategic Shot (Scordeo's Edge) or Sharpshooter's passive, they are not ranged in reality.
Like in the other topic, I list here only the 100% chance to proc a Truly Ranged Effect :
Thundercrack Pistol : Overload (paralize on crit) vs fortitude
: Conductive Blast (not the upgrade)vs reflex, 1/rest
Xefa's Empirical Explication : Matter Repulsion (knocked back on crit, vs fortitude
: Inexplicable Mass ( Knock prone on crit), vs fortitude
Spearcaster : Forceful Impact (50% chance to knockback and daze on hit), vs fortitude
: Arcane Bolt (15% chance to cast Minoletta's missiles on crit),
; Pinning ( 20% chance to immobilize on hit), vs fortitude
: Skewer (multiple target bolt) 2/rest, vs defl. & fortitude for immoilized and pushed
Watershaper Focus : Brackish Arc ( Sicken on crit) vs fortitude
There are some others like with smaller chance or specific target like A whale of a Wand (Beast Imagined, Sea Stories, Woven Waves (5% chance for each effect to proc), Keybreaker Scepter (Revelation, frighten kith on crit), The Eye of Wael (Illusive Spell, 5% chance to cast a random spell on hit, Shrouded Strike, 10% chance to random affliction on target on crit),Amaliorra (Bend the Will & Break the Will on crit vs kith or wilder, Claim the Will & Claim the Husk abilities), Dragon's Dowry (Serpent's Rage ability), The Weyc Wand (Muddling Bolts, 25% chance to confuse target on crit), Windsong (Loose the Wind, 30% chance to deal freeze damage on crit), Aaminaa's Legacy (precison Impact and the upgrade), Amira's Wing (Forceful Gust, 5% chance to interrupt and knock prone on hit), Veilpiercer (Disruptive Arrow ability), and Rod of the Deep Hunter (Crashing Surf Ability).
More funny, there is also Preparing the Offering (ability from Sanguine Greatsword), Ball Lightning (Lord Darryn Voulge) and Necrotic Heart (and upgrade) from Voidwheel ! Also, The Pain Persits (not Instruments of Pain) is Ranged Weapon, and fists bounces (but dont trigger Swift Flurry anymore).
All these effects are Ranged - Weapon, so they trigger Avenging Storm and bounce with Diving Flight, but also profit to some bonuses like Marksman (Ranger) and Shootist ( Alcina's Tricorn)*.
More clearly, Conductive Blast is really devastating with a ranger (especially with Avenging Storm, each hit from the ability cause 1 lightning and bounce with a lightning, an each hit and bounce can crit, causing Overload that cause one lightning and bounce with another lightning, and can also crit causing a new Overload (an new lightning) and bounce (with a lightning) etc.
Xefa Empirical Explication can, with Driving Flight and Avenging Storm, create a lightning "cone", and with Whirling Strike and really good acc, it is like a Lightning Show. Of course, it is not the "explosion" that Hand Mortar make, but it is valuable : 4*2 bullets that can trigger 2 effects per bullet on crit that bounce and can create 2 new effects on crit that bouce etc with one lightning for each proc and bounce.
The Watershaper Focus is also really great because of the modal, the +1 bounce, Driving Flight and so the 3 AoE that can proc some crit that trigger Backish Arc that bounce and can also crit, causing a new layer of Backish Arc, that bounce etc. Of course, witout Avenging Storm, that is not really impressive, but with it, that look like one of the most powerful weapon for ranger.
* : about Shootist from Alcina Tricorn, that work also for most of the spells, and with the combinason of Sky Dragon Wurm (+3acc for >4m target), Boras (+5acc with Spells), Sagani Ressentiment (+2acc for >4m target), the wearer gain +15acc with spells. In this case of the wearer is the ranger, +15acc with weapon (+10 above + ring of the Marksman) and +15acc with Avenging Storm.
