In Warhammer 40k 8th Edition, Orks commonly have an ability called "Dakka! Dakka! Dakka!". The rule reads:
Each time you roll an unmodified hit roll of 6 with a ranged weapon made by this model, that hit roll succeeds regardless of any modifiers. [...]
I am very confused by the wording, and don't exactly know how to apply it. Imagine I have an Ork with this ability and a ballistic skill of 5+, and they would fire eight shots at an enemy unit. The dice return as follows:
1 1 2 3 4 5 6 6
Since no modifiers were applied, to me this seems like an "unmodified hit roll", and three hits would be counted, out of which two (the 6's) would be affected by "Dakka! Dakka! Dakka!". Is this understanding correct?
Now imagine that the weapon my Ork was affected by some ability that would allow them to add +1 to their hit rolls. If the same dice result would come up, it would now result in 4 hits, but none of those hits would be affected by "Dakka! Dakka Dakka!". Is this understanding correct?
And if so, would that mean that, for the sake of "Dakka! Dakka! Dakka!", every "buff" to my hit rolls would actually disable this very useful skill?
