Right after the nomad camp in the divine era, there’s a large patch of dark ice (deep blue).
Attacking with shield throw while standing inside this patch of ice seems to prevent the projectile from firing (cooldown begins right away).
Attacking from outside the ice (say, from the snow) allows to throw the shield over the ice, though.
Hey!
I can upload a screen shot, but it is indeed the very same area.
Projectiles fired from inside seem to vanish, while projectiles fired from the outside can cross.
I’ll try to get a ricochet off, and report back.
EDIT: I tested it again, and projectiles fired at monsters vanish too. I’ll try to capture it.
Firing at point blank does hit.
