Wailing Caverns' Embrace of the Viper — a hidden 5-piece bonus turns druids into a serpent

The Wailing Caverns set Embrace of the Viper has a 5-piece bonus that is not on the tooltip: a druid wearing all five pieces turns into a serpent in Cat Form. Blizzard's Zirene added that the serpent is a different color for each druid race, and slinks down to slither along the ground while prowling.

Where the pieces drop

• Belt of the Fang — Lady Anacondra
• Leggings of the Fang — Lord Cobrahn
• Armor of the Fang — Lord Pythas
• Footpads of the Fang — Lord Serpentis
• Gloves of the Fang — trash inside the dungeon

The four Fang lords are also what unlocks Mutanus at the end, so one full clear gives you a shot at four pieces. See the Wailing Caverns guide for the route and the druid talent calculator for a Cat Form build.
