Thanks, thejeff! That sounds like a reasonable explanation.
chrispedersen, I know the area effect is random and can miss units. What I'm trying to determine is if the targeted square is always hit as part of the blast. I think it's always hit (as the first blastsqr affected), so I believe a solo unit should always manage to bless itself.
If someone can provide a save game or debug log proving otherwise, I will change my beliefs immediately.
