Hex

A Hex is a type of spell that can be cast on a target and armor level, their energy regeneration or their movement speed while the hex is in effect. Many Hexes are available to Mesmers and Necromancers, and a few are usable by Elementalists.

When an ally has a hex cast on them a purple down arrow will appear on their health bar in the party window. If the player suffers health degeneration as a result of a hex, then his entire health bar will turn purple and begin to decrease.

Monks have a few spells capable of removing Hexes, such as Smite Hex.
