Guild Wars 2

Explosive Shot does not gain anything from traits that affect explosions. Havn’t looked through all traits but I know for sure these traits does NOT affect it:

Steel-Packed Powder (Explosives +25)
Explosive Powder (Explosives +20)

Quaggan has looked into this. Quaggan knows that explosive shot is tied to the Firearms Trait.

Quaggan knows this is weird, but explosive shot hurts Quaggan. Boo!

Foo! Quaggan will look later when Quaggan learns how to be engineer for other quaggans.

StygSec.7163:

Quaggan knows that explosive shot is tied to the Firearms Trait.

Dear Quaggan.

If you look at it like that, all weapon sets including bomb kit and grenade kit is tied to firearms, since firearms grants you more critical hit chance = more damage with said kits

An explosion is an explosion and should be affected from traits affecting explosions.

Coo, Foo and Boo

Turret explosions don’t get anything from Explosives traits, either, whether detonated or destroyed while affected by Accelerant-Packed Turrets.

Edit: As far as I know, this is a known bug (both Explosive Shot and A-PT failing to activate Explosives traits), but I don’t expect it to get fixed earlier than maybe March, at the rate they’re going.
