This skill, the thief shortbow #5 skill, has been quite buggy since late beta. Early in beta (pre-BW1) it seemed to work quite well, you could use it for great mobility, but from BWE1 onwards it’s been pretty useless. It can no longer cross gaps, even though warrior and elementalist skills can do so. it can no longer be used to climb up on platforms above you, which was possibly its most interesting feature. And even when you’re trying to teleport horizontally on relatively flat ground, it still constantly gets stuck on a little pebble or something.
