Guild Wars 2

Firstly, Forceful Explosives doesn’t benefit grenades, so you can change that to Shrapnel or Incendiary Powder.

Secondly, I’ve never seen a successful FT & grenade combo build. If you’re only bringing FT for its utility (aoe blind & knockback & fire field) then Juggernaut is a waste anyway. Especially because 1/2 of its benefit is only realized by staying in it to let the might stack. Better to take Deadly Mixtures to benefit EG as well. However, again if neither FT nor EG are being used for damage but rather as utility, then what’s the point of taking either of those traits? You’re in full celestial I see, so I’m guessing a power/condition hybrid? I’m trying to figure out your playstyle with this build.
