Guild Wars 2

Applying AOE damage directly underneath the mortar in the southwest tower on the Alpine map appears to cause damage to the mortar above it. In the attached screen grab there is a smaller red circle above the larger one underneath the outcropping. It looks like the AOE is wrapping around the structure.

More of a weird design decision than a bug. AoEs are actually orb shaped so radius extends in all directions (I’m assuming this was to make it impossible to just jump over stuff like lava font to avoid damage), picture those red rings as the points where the terrain meets the orb and that’s where the attacks land. A good way to see what I mean is to use something like Berserker torch 5 near walls and watch how the AoEs appear on them and any super low ceilings, or overload fire on a tempest and jump which will make the aoe look like it’s shrinking slightly while you’re in the air.
