You are correct that it doesn't add damage to the arrows, but I've found it to be pretty effective at inflicting afflictions on most troops. Arrows doing only 1 or 2 points of damage with a D9 or 10 bless have a considerable chance of making you lose an arm, get a chest wound, gain battle fright, and all kinds of other nasty things you don't want to happen as you're charging into battle. You can also do mean things like Fire and Flee with death blessed archers to really discourage elite armies from pressing into your territory. Works well on javelins to, and they're a lot more common on holy troops.
