Bug

A rare weapon found exclusively in The Rift, Bug replaces your basic attack with Metronome — casting a random spell each time you use it. The unpredictability is the whole point: every attack could be anything from a heal to a massive damage spell, making Bug a chaotic but potentially powerful pick for players willing to gamble on the outcome. Works best when your build can tolerate variance and you have other reliable tools to fall back on when the random roll lands poorly.
