If the radius was increased even to the scale of caltrops, it would be a game changer for the skill. I wouldn't even care about the up time of the skill. I main a necro so I could honestly go on about the class, but I feel this would be an easy buff to implement because of the radius coding already in the game, so just slap those same measurements to boneyard.
