Dao of Pow

Dao of Pow is the strongest flail in the game and was added in the 1.1 update. It is coloured black and white in a Taijitu or "Yin Yang"-style design commonly associated with Taoism, with eight spikes around the edge. The Dao of Pow also has a maximum range almost twice as long as the Sunfury.

The Dao of Pow has a chance to give the Confused debuff to most enemies it strikes. Confused enemies will have a large purple question mark above them and will move away from the player, and any enemies with ranged attacks such as Skeleton Archers will run away rather than fire at the player. Teleporting enemies such as Chaos Elementals will still try to teleport towards the player, but promptly run away again...

Trivia
The Tooltip is a play on words on the phrase "Find your inner peace", referring to the inherent objective that Taoists should strive towards. The "pieces" may be a reference to the Light and Dark Shards used to create it. Alternatively, the name might reference the weapon's ability to rip enemies to "pieces".

The name Dao of Pow may be referring to the book The Tao of Pooh.

The word "Dao" is never written by Taoists, but "Tao" is pronounced "Dao".

Considering the ingredients needed to make it, it presumably represents a 'duality' between the Corruption and the Hallow.

The tooltip "find you inner pieces" might be a spelling mistake, as it says "you" instead of "your".
