death bless

[Shardphoenix]

i guess it means your blessed troops inflict afflictions on enemies?

Yes. AFAIK, it also works for spell damage, so some death bless could be EEEEEEVIL on sacred mages casting evocations. Even if enemies live through it - they are crippled for the rest of their (short) lives.
Major D bless isn`t suitable for nations with blessable thugs, because it replaces any useful magic effect on thug`s weapon, like this AoE damage on Fire Brand. And those 2 points of damage from major D bless are MR negated.
I think, high D bless is the worst high bless in game. If you want higher damage - get high F or low B.
