The devil is in the details
I often use that phase. I use it cause it is a good phase, simple but powerful. In gaming life I recently found my character dropped to 0 hit points. It was looking like a TPK (Total Party Kill) as I was the healer and being down makes it really hard to heal folks. So I was looking at my character sheet looking for a way out and noticed that my armor gave me resist 5 psychic. Turned out I took 3 points of psychic before the blow that took me to 0. Our DM was extremely kind and allowed me to negate the damage from the psychic attack, which in turn allowed me to stay in the combat and heal folks. Found the devlish detail that time!
