This is nothing but a very long winded "Thanks" post which are best kept to PMs to keep the thread clear and on topic.

Thanks for the response. I was indeed referring to tooltip damage and you're definitely correct:
Whilst reading the description for communion, I was under the impression that the 2% bonus only took effect whilst an aura was active. I took the stats from my initial post with no aura/blessing/seal at all, and it's exactly the same as the tooltip damage listed on my armory page (which I assumed would not include any aura modifiers).
Oh well, I'm happy that I know what the answer is now. Thanks again!
