Re: Dorygoon's 19 Warlock Guide
There have been times when it lets me jump 2-3 times in a row without triggering a cooldown, but it's rare.
On my warlock the jump in place Demonic Leap does trigger a cooldown but it's reset as soon as I land, preventing me from leaping twice consecutively. However, once in every 10 (or so) in place leaps will the cooldown reset mid-air and allow me to do the second consecutive leap. As Dory mentioned, Demonic Leap has some weird mechanics, similar to that of a druid's wild charge while in Travel Form.
