I have tested multiple interactions with the Hunter's "Quickfall" ability on the "Trapper's Ambush" Aspect. The Quickfall ability fails to register as a melee on multiple perks, exotics, and fragments despite the smoke bomb base ability registering correctly as a melee. Here are the results of my findings: 1. Interaction: [b]Void Class Fragment - Echo of Leeching[/b] a. Ability: [i]Smoke bomb[/i] - Result: [i]Gives health and triggers regen on kill with direct hit and explosion[/i] b. Ability: [i]QuickFall[/i] - Result: [i]Fails to give health or trigger regen on kill[/i] 2. Interaction: [b]Void Class Fragment - Echo of Exchange[/b] a. Ability: [i]Smoke bomb[/i] - Result: [i]Gives grenade energy on kill with direct hit and explosion[/i] b. Ability: [i]QuickFall[/i] - Result: [i]Fails to give grenade energy on kill[/i] 3. Interaction: [b]Exotic Helm - Assassin's Cowl[/b] a. Ability: [i]Smoke bomb[/i] - Result: [i]Gives invisibility and health regen on kill with direct hit and [/i]explosion b. Ability: [i]QuickFall[/i] - Result: [i]Fails to trigger health regen, invisibility untestable due to aspect[/i] 4. Interaction: [b]Exotic Arms - Sealed Ahamkara Grasps[/b] a. Ability: [i]Smoke bomb[/i] - Result: [i]Reloads weapon on direct hit and explosion[/i] b. Ability: [i]QuickFall[/i] - Result: [i]Fails to reload weapon on hit[/i] 5. Interaction: [b]Weapon perk - One-Two punch[/b] a. Ability: [i]Smoke bomb[/i] - Result: [i]Tricky, but can get the buff to work on direct hit and smoke explosion, but direct hit will consume before explosion goes off[/i] b. Ability: [i]QuickFall [/i]- Result: [i]Fails to buff any aspect of this.[/i]
