Hex

A Hex is a type of spell that can be cast on a target and negatively affects some property of the target, such as their armor level, their maximum health or their energy regeneration. Hexes are usually only effective for a period of time. Hexes are commonly used by Mesmers and Necromancers. 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 their entire health bar will turn purple and begin to decrease.

Hexes can be removed using monk spells such as Smite Hex.
