Question about shield of courage
Team Deathmatch for PvP – Raise the AoE cap for WvW – More unique events for PvE
If a pulsing-aoe damage (such as another guardian’s symbol) is placed on you, and the center of the aoe is in front of you, then you will block it.
The other possibility is that if you’re within the aoe, but caster of the aoe is in front of you, then you’ll block all of the damage from the aoe regardless of your positioning relative to the aoe.
I think the first case is how it really is, but am not completely sure as I haven’t extensively tested this.
