The deep spirituality — some say superstition — of the trolls requires them to perform elaborate rituals, sometimes while on the move or during battles. Some of these rituals, like the snake dance, involve quick, flexible movements and contortions. Trolls in standard armor quickly discovered that their hampered movements interfered with the rituals.
Troll witch doctors developed the armor of the snake dance to combat this problem. The armor appears made of snakeskin and fits tightly against the body. Numerous small metal charms and beads adorn the armor, both affording more protection and evoking spiritual significance.
Forsaken arcanists, after viewing the troll armor, designed similar suits of plain black studded leather armor with identical properties. Forsaken rogues favor this armor, and it imbues their movements with a dancelike feel.
