Guild Wars 2

Zibbeh/Deyka is a guildie and I can vouch that he own both accounts.

Before I explain my findings, I will define two key things I will talk about to prevent from confusion people.

The Wall: This is where the spell animation appears, it is visible.

The Combo Field: This is the area where you can shoot your projectiles, and use other combo finishers to gain boons and added effects onto your abilities. It has the same shape and direction as the wall.

1. The combo field itself doesn’t go on where the wall is placed, instead it goes on top of the necromancer’s location (you cannot see it). Keep in mind that you still get the protection buff for walking over the wall itself, but the combo field is elsewhere.

2. The Spectral Attunement, the trait increases the duration of the wall, but not for the combo field.

Would really appreciate it if someone else also tests this, I have done so with every combo finishers.
