Shutdown

From Guild Wars Wiki

Shutdown means to render a foe useless in terms of their ability to affect the battle. A spell-caster who cannot get off their spells or a Warrior who cannot damage their intended target are considered to be "shut down".

Forms of shutdown include:

• Interrupts
• Disabling of skills (via spells like Blackout or Power Block)
• Use of conditions to deny certain roles; constantly blinding a Ranger, crippling a Warrior trying to chase his target, or dazing a spellcaster are examples of shutdown via conditions.
• Use of hexes to severely limit a player's damage output or skill usage, for example Faintheartedness on a Warrior or Shame on a Monk.
• Knockdowns (via Gale or Shock)
• Energy denial
• Snare (tactic)
