Gunslinger Build (Lv. 10-200)

I have a question, is there any gunslinger skill that has no minimum range? It looks like cooling, burning, and fake shot has no min range, or maybe it's just that GSs have very small minimum range to begin with.

Also, exactly how many octopusses can you have out at a time? One of the videos on the first post had 3 out at once, while i had thought the max was 2 before then.
