No, Ki blast, but not only, in general DC = Speed, in DB. But where AP come from? also how much time we saw a villain or just someone literally smoothing the ki blast and sending it somewhere else.
some examples. I chosed from DBH and DBS because those dudes are 3-A, Low 2-C and even 2-A. their Ki explosion didn't destroy a equivalent area of their AP, but it is undeniable that their attack was on a greater range than what it did, that is, it is basic, it was a DC that went from 3-A to 2-A but without effective range, maybe I expressed myself badly but I'm talking about the range
