Dao of Pow

The roll happens once per swing, not once per enemy. When it lands, everything the flail touches on that swing turns around and wanders off. When it misses, nobody is affected at all. It lands most of the time, so in practice a crowd standing between you and where you want to be simply stops being a problem.

Confused enemies drift instead of chasing, and that is dead time you should be filling. Imbue the flail with a flask or fight over something that ticks, and the wandering does the work for you. It is available the moment you break into Hardmode without killing anything first, so it covers the awkward stretch before the mechanical bosses. Wyverns are a good target, since a confused one loses its charge entirely.

It is the melee corner of a small trio built from paired shards, alongside the Onyx Blaster and the Sky Fracture. Those two take darkness and light, and this one takes balance, which is where the yin-yang sprite and the Daoist naming come from. The tooltip is a pun on finding your inner peace.
