Does damage from a F9 bless stack with D9 ?

[Teraswaerto]

Afflictions are caused by damage, so 0 damage will not cause random afflictions, even with 350% chance of afflictions. The more damage a single attack does the higher the chance of causing an affliction. This is also affected by the max hitpoints of the creature being damaged, the more HP the lower the chance of afflictions.

I'm pretty sure some attacks, like Koppo, will cause their affliction on hit even if there is no damage.
