It came up in the last game about Courageous Anthem1.
Player Core page 428 states that:
When you’re playing in encounter mode and using a grid, areas are measured in the same way as movement (page 420), but areas’ distances are never affected by difficult terrain. Standard or greater cover can apply against areas, but not lesser cover.
Bending around corners:
Not bending around corners:
Line of Effect says you need an unbroken path, but that contradicts "areas are measured in the same way as movement", and make no sense for things that do not fly out in straight line like shrapnel. Noise Blast should not care about corners at all, and arguably Fireball neither. Courageous Anthem's predessessor (Inspire Courage) had a Verbal component, and as we know sound does bend around corners.
I know GMs could and should make individual calls, like Earthquake should not even be stopped by solid walls. But currently Foundry (our virtual tabletop) has the non-bendy version, and most GMs are just accepting it.
Is there some other support for the bendy behavior?
- I know it is a 60 foot emanation, but I did not want to draw that much. Pretend it is a 3 action Heal
