Guild Wars 2

I’ve been reporting this bug since fractals have been released through the in-game tool. In the dredge fractal, the “elemental turrets” cannot be damaged by most necromancer weaponry.
-minions all get “obstructed”
-the axe gets “obstructed”
-the scepter gets “obstructed”
-the staff gets “obstructed”
-the focus gets “obstructed”
-even the focus and offhand dagger get “obstructed”

They are annoying, indeed.
You need AoE effects to damage them. Just bring some consumables with you as necromancer or mesmer.
