Wither

Progression

 * 1) Duration is measured in seconds.

Usage

 * In combination with Malaise and the Mesmer hex Ether Lord this spell can cause devastating energy degeneration.
 * In PvE this skill combined with Malaise on an enemy spellcaster will completely shut down his energy regeneration. If he continues casting he will often fall below 5 energy (the lowest cost a spell can have) without reaching 0 and be shut down for the rest of the duration. Therefore don't use additional energy burning skills on him and tell your team members (especially mesmers) to not do so as well, as this would bring your enemy down to 0 energy and cancel both hexes!
 * Tip: to remove this hex quickly when it is cast on you, swap your weapon (staff/wand/focus) to a non-energy weapon.
